An evidence-based approach to basal cell cancer

Basal cell cancer is relatively common. Patients often first present to the primary care provider with complaints of an abnormal skin lesion. When diagnosed early, it has an excellent prognosis, but if there is a delay in diagnosis, the tumor can advance and lead to significant morbidity. Basal cell cancer is best managed by an interprofessional team that includes a dermatologist, mohs surgeon, plastic surgeon, nurse practitioner, primary care provider, and a dermatopathologist. Basal cell carcinomas typically have a slow growth rate and tend to be locally invasive. Tumors around the nose and eye can lead to vision loss. In most cases, surgical excision is curative. However, because recurrences can occur, these patients need long-term follow up.

General Principles In Outer Nose Repair

Most of nasal skin is of the sebaceous type. Whenever possible, scar lines should be placed along relaxed skin tension lines. Aesthetic units of the nose need consideration although tumours do not respect their borders. Aging affects the nose anatomy. Characteristic symptoms are frown lines , transverse crease on the nasal root, drooping of tip of nose, and deepened nasolabial folds. Skin diseases of elderly, like rosacea and rhinophyma can interfere with surgical techniques.

The skin covering the bony parts is highly movable, while the skin over cartilage parts is thicker, tighter and bound to the cartilage. Healing by second ary intention of convex surfaces like the nose tip should be avoided since healing often is delayed and may lead to uneven scars.

What Are The Subtypes Of Basal Cell Carcinoma

Posted on June 27, 2020 in Basal Cell Carcinoma

One of the most common types of skin cancer is basal cell carcinoma . About 4 million people are diagnosed with BCC each year in the United States. Basal cells are one of the main types of cells in the top layer of the skin. BCC can occur when the basal cells get damaged by ultraviolet radiation, which leads to uncontrolled growth. Those who get sunburns are more likely to develop skin cancer.

Not all BCC skin cancers are the same. There are many subtypes that are diagnosed, and they behave and appear differently.

Who Gets Infiltrating Basal Cell Carcinoma Of Skin

  • Infiltrating Basal Cell Carcinoma of Skin is an uncommon skin cancer that generally affects elderly or older adults some cases rarely develop in children too
  • It can occur in both males and females however
  • Among the older age group, males are affected more than females
  • In the younger age group, females are affected more than males, which may be attributed to their tendency to acquire sun-tanned bodies or visit skin tanning parlors more
  • This condition is observed worldwide across all racial and ethnic groups however, lighter-skinned individuals are more prone to Infiltrating BCC of Skin than darker-skinned individuals
  • Other Risk Factors For Sporadic Bcc

    Association of Multiple Aggregated Yellow

    The incidence of BCC is much more common in individuals who have received a solid organ transplant, in whom herpes virus like DNA sequences have been demonstrated, and in whom tumors appear to have an increased tendency for recurrence and metastasis. In concert with this more aggressive behavior, the histologic types are different in patients with immune suppression in whom infiltrative growth BCC is more common than nodular and/or superficial variants. In contrast, superficial BCC predominates in individuals with renal failure, diabetes mellitus and human immunodeficiency virus infection.

    What Is Nodular Basal Cell Carcinoma Of Skin

    • Basal Cell Carcinoma of Skin is a malignant cancer affecting the skin. It is a slow-growing tumor generally observed in older individuals, in both men and women
    • This malignant carcinoma, which may be present as a lesion on the sun-exposed areas of the body, has the potential to metastasize to the lymph nodes
    • Nodular Basal Cell Carcinoma of Skin is the most common type of BCC that is present as nodules on the skin, usually in the head and neck area
    • Some nodules may grow to large sizes and ulcerate. They can also infiltrate into the adjoining soft tissues and nerves. Larger tumors also have a greater tendency to recur after treatment
    • The cause of Nodular Basal Cell Carcinoma of Skin is unknown, but factors such as chronic sun exposure, smoking, and ionizing radiation, etc., are known to contribute towards its development. Also, fair-skinned Caucasians have a greater risk than dark-skinned Africans and Asians
    • Any combination of chemotherapy, radiation therapy, and invasive procedures are used to treat Nodular Basal Cell Carcinoma of Skin. Small-sized tumors and tumors that have not metastasized can be cured through appropriate skin surgery
    • The prognosis for metastatic tumors depends upon many factors including the stage of the tumor, health status of the individual, and treatment response. The prognosis may be guarded

    Benign And Malignant Tumors

    Several benign and malignant tumors can have a clinical appearance similar to that of SGC. These include BCC, SCC, melanoma, Merkel cell carcinoma, lymphoma, sweat gland neoplasm, junctional squamous papilloma, hereditary benign intraepithelial dyskeratosis, metastatic carcinoma, and other rare tumors.1

    Basal cell carcinoma

    The nodular BCC is more common on the lower lid and is white rather than yellow. BCC is also more likely to become ulcerated than SGC. Although diffuse sclerosing BCC may closely simulate SGC, it very rarely exhibits diffuse invasion of the conjunctiva. Histologically, BCC typically shows peripheral palisading of nuclei and retraction artifact that are not seen in SGC.

    Squamous cell carcinoma

    SCC is more superficial and lacks a yellow color. Conjunctival intraepithelial neoplasia can be very similar to diffuse epithelial invasion by SGC, except for eyelid involvement, which is less likely to be present in SGC. Histopathologically, SCC is the lesion most often confused with SGC.6,14,15 Unlike SGC, SCC cells have more abundant eosinophilic cytoplasm, lack lipid vacuoles, and demonstrate eddy formation and keratin cysts.

    Melanoma

    Nodular or diffuse cutaneous melanoma in the eyelid or conjunctiva can usually be distinguished from SGC by its black or brown pigmentation, but amelanotic melanoma can resemble SGC.

    Micronodular Basal Cell Carcinoma

    Clinically found elevated or flat infiltrated tumors. They ulcerate seldom and have yellow-whitish color when they are flat, ostensibly clear outlines and thick at palpation. The most common localization is the skin of the back. On histology this tumor demonstrates small rounded nodules of basaloid cells and minimal palisading .

    Infiltrating Basal Cell Carcinoma of Skin signs and symptoms may include:

    • Infiltrating BCC of Skin is a slow-growing malignant tumor. The tumor is a typical skin lesion, with thickened skin, presenting as a poorly-demarcated plaque
    • The surface of the plaque may be red, if intact. Else, it may appear as an ulcer, if the surface is eroded
    • It is typically observed on sun-exposed areas of the body common sites include the head and neck region, arms and legs, etc.
    • The tumor may be solitary or many in number. In children, if it is associated with basal cell nevus syndrome, then multiple lesions may be observed
    • Some Infiltrating BCC of Skin may have pigmented appearance and may resemble a melanoma
    • Most lesions are less than 1-2 cm, but some may grow to larger sizes of even 10 cm
    • The carcinoma has a tendency to penetrate deep into the subcutaneous tissue
    • The lesion may grow and there may be itching sensation, ulceration, and bleeding

    Am Fam Physician. 2012 Jul 15 86:161-168.

    Nonmelanoma skin cancer, which includes basal cell carcinoma and squamous cell carcinoma, is the most common cancer in the United States. Approximately 80 percent of nonmelanoma skin cancers are basal cell carcinoma and 20 percent are squamous cell carcinoma. Although the National Cancer Institute does not formally track the incidence and prevalence of nonmelanoma skin cancers, multiple longitudinal studies indicate that the incidence has risen sharply over the past two decades.1

    Infiltrated Basal Cell Carcinoma

    This version of basal cell carcinoma is presented as thin bundles of basaloid cells with nest-like configuration located between the collagenous fibers on the dermis and infiltrating in the depth. Clinically, it is a whitish, compact, not-well defined plaque . The most common localization is in the upper part of the trunk or the face. Seldom had the paresthesia or hyperesthesia as a symbol of perineural infiltration appeared, especially when the tumor is localized on face. This clinical version is often underestimated when the borders of surgical excision are estimated. Histologically this variant is presented as thin, nest-like bundles of basaloid cells infiltrating in the dermal collagenous fibers .

    Pathology Outlines

    This version occurs as erythematous plaque with different sizes . It is about 10-30% of basal cell carcinoma and occurs on the body skin. There is an erythematous squamous plaque with clear borders, pearl-shape edge, superficial erosion, without tendencies for invasive growth . The regression areas are presented as pale sections with fibrosis. The differential diagnosis includes Bowen disease, psoriasis, or eczema. The numerous superficial BCC are met often in case of arsenic exposure. Histology showed nests of basaloid cells located subepidermally, with clear connection with the basal layer of the epidermis and no infiltration of tumor cells in the reticular dermis .

    Who Gets Basal Cell Carcinoma

    Risk factors for BCC include:

    • Age and sex: BCCs are particularly prevalent in elderly males. However, they also affect females and younger adults
    • Repeated prior episodes of sunburn
    • Fair skin, blue eyes and blond or red hairnote BCC can also affect darker skin types
    • Previous cutaneous injury, thermal burn, disease
    • Inherited syndromes: BCC is a particular problem for families with basal cell naevus syndrome , Bazex-Dupré-Christol syndrome, Rombo syndrome, Oley syndrome and xeroderma pigmentosum
    • Other risk factors include ionising radiation, exposure to arsenic, and immune suppression due to disease or medicines

    How Is Nodular Basal Cell Carcinoma Of Skin Treated

    In general, the treatment of Basal Cell Carcinoma of Skin depends upon a variety of factors including:

    • The subtype of BCC
    • The location of the tumor
    • The number of tumors
    • The size of the tumor
    • Whether the tumor has metastasized

    A combination of treatment methods may be used to treat Nodular Basal Cell Carcinoma of Skin. The type of surgery may include:

    • Shave biopsy of skin: This procedure is used for small tumors. There is no requirement of sutures after the surgery
    • Excision of tumor: In this procedure, the tumor and surrounding tissue are removed with clear margins. Depending upon the amount of skin removed, surgical sutures may be necessary
    • Mohs surgery: In this procedure, the tumor is removed layer by layer precisely, until clear margins are achieved. Each layer removed is examined under a microscope through a âfrozen sectionâ procedure, for the presence of residual tumor

    In most cases, a surgical removal of the entire tumor is the preferred treatment option. This can result in a cure.

    Other techniques to treat this skin cancer may include:

    • Cryotherapy: Here the tumor tissue is destroyed through a freezing technique. Typically liquid nitrogen is used to freeze the tumor
    • Topical creams, such as 5-fluorouracil cream and imiquimod cream, are two examples that can be used for topical treatment. These creams may be applied for several weeks, which slowly destroys the tumor

    Effective Options For Early And Advanced Bcc

    When detected early, most basal cell carcinomas can be treated and cured. Prompt treatment is vital, because as the tumor grows, it becomes more dangerous and potentially disfiguring, requiring more extensive treatment. Certain rare, aggressive forms can be fatal if not treated promptly.

    If youve been diagnosed with a small or early BCC, a number of effective treatments can usually be performed on an outpatient basis, using a local anesthetic with minimal pain. Afterwards, most wounds can heal naturally, leaving minimal scarring.

    Options include:

    Basal Cell Skin Cancer

    BCC is the most common type of skin cancer. About 75 out of every 100 non melanoma skin cancers are BCCs. They develop from basal cells and these are found in the deepest part of the outer layer of the skin .

    They develop mostly in areas of skin exposed to the sun, including parts of the face such as the nose, forehead and cheeks. Also, on your back or lower legs.

    They are most often diagnosed in people who are middle aged or older.

    Doctors might also call a basal cell cancer a rodent ulcer.

    There are a number of different types of BCC. Each type can look and behave differently. They include:

    • nodular basal cell skin cancer
    • superficial basal cell skin cancer
    • morphoeic basal cell skin cancer – also known as sclerosing or infiltrating basal cell skin cancer
    • pigmented basal cell skin cancer

    Nodular basal cell cancer is the most common subtype.

    It’s very rare for basal cell skin cancer to spread to another part of the body to form a secondary cancer. It’s possible to have more than one basal cell cancer at any one time and having had one does increase your risk of getting another.

    Infiltrative Basal Cell Carcinoma

    Infiltrative basal cell carcinoma is an aggressive type of skin cancer that requires surgical treatment. Subtypes of infiltrative basal cell lesions include micronodular carcinoma and morpheaform carcinoma.

    Causes: Infiltrative forms of basal cell cancer, like those of the nodular and superficial types, are linked to both genetic factors and environmental factors such as prolonged sun exposure in youth.

    Symptoms: The symptoms of infiltrative basal cell lesions vary according to subtype. Micronodular lesions are typically firm, yellowish-white in color, and have a distinct border. Morpheaform lesions resemble plaque or scar tissue, have vague and far-reaching borders, and are prone to crusting and bleeding.

    Diagnosis and Treatment: A thorough skin biopsy is necessary for this type of basal cell cancer, as infiltrative lesions are visually easy to mistake for other non-cancerous forms of scar tissue. Surgical excision with margin examination, radiation therapy, and Mohs micrographic surgery are the most effective treatment options.

    Once a patient has been diagnosed with one of the types of basal cell cancer, he or she can discuss treatment options with medical professionals and can proceed with having the cancer removed. Because several effective basal cell surgical procedures and medication options are available, patients who are diagnosed while the disease is in early stages often have a very good prognosis.

    Ask The Expert: Why Am I Having Surgery To Remove A Small Basal Cell Carcinoma

    Dermpath Made Simple

    Although the nonmelanoma skin cancer basal cell carcinoma is rarely life-threatening, it can be troublesome, especially because 80 percent of BCCs develop on highly visible areas of the head and neck. These BCCs can have a substantial impact on a persons appearance and can even cause significant disfigurement if not treated appropriately in a timely manner.

    The fact is, BCCs can appear much smaller than they are. On critical areas of the face such as the eyes, nose, ears and lips, they are more likely to grow irregularly and extensively under the skins surface, and the surgery will have a greater impact on appearance than might have been guessed. Even a small BCC on the face can be deceptively large and deep the extent of the cancer cannot be seen with the naked eye.

    If such a BCC is treated nonsurgically , the chance of the cancer recurring is high. Unfortunately, treating a BCC that has returned is usually much more difficult than treating it precisely and completely when initially diagnosed.

    BCCs on the trunk, arms and legs that cause concern are typically larger in size, but even a small BCC in these areas can have an irregular growth pattern under the skin if the initial biopsy shows the tumor is aggressive. In addition, a small BCC in an area previously treated with radiation may be much more aggressive than it appears on the surface. Again, treating such a tumor nonsurgically is likely to leave cancer cells behind.
