Lentigo Maligna Melanoma

Collision tumors are defined as two histologically different tumor types that arise at the same anatomical location. According to the literature review performed, there are reports of 27 cases of collision tumors involving lentigo maligna melanoma (LMM) in-situ and basal cell carcinoma (BCC). In the absence of melanocytic extension beyond the lamina propria of the BCC compartment, mixed tumors are considered as melanoma in-situ colonizing the BCC, rather than invasive melanomas. We report an uncommon case of collision of BCC with LMM, two primary skin tumors that are seen in patients with significant sunlight exposure. In our case, the patient is a 91-year-old male presented with a translucent plaque with areas of brown pigmentation on his left lateral canthus. He had a history of multiple BCCs, squamous cell carcinomas and an invasive melanoma of right cheek. Given the clinical impression of BCC, the lesion was curetted. Histological examination demonstrated melanoma in-situ heavily infiltrating the dermal nodules of BCC. Deposits of melanin pigment were scattered throughout the tumor. The BCC contained about 50% atypical melanocytes. Further immunohistochemical evaluation with melanocytic and epithelial markers (melanin A, SOX-10, pan-cytokeratin and p63) confirmed the diagnosis. An unequivocal independent invasive melanoma component was not identified in this material. The collision of BCC and LMM is very rare.  However, given the sun-damaged changes promote both tumors, their development at the same site, although unexpected, can be explained. Since the prognosis of the two entities is independent, wider excision to exclude invasive malignant melanoma is indicated.

Basal Cell Carcinomas

Background: Basal cell carcinomas of the periocular area present a particular challenge because of the likelihood of damage to vital structures. Objective: More than 10-years experience of treating basal cell carcinomas by Mohs micrographic surgery was reviewed. Methods: Chart analysis of 233 periocular basal cell carcinomas was performed. All patients were contacted either in clinical follow-up or by telephone review. Results: Two hundred and thirty-three periocular basal cell carcinomas were analyzed out of a total of 3,192 basal cell carcinomas treated during this period (7.3%). Patients ranged in age from 17 to 102 years with a mean age of 58.8 years and a median of 59.0 years. Of the patients, 54.5% were female. Mohs micrographic surgery was the prime therapy in 177 patients (75.9%). Of the lesions, 48.5% occurred in the medial canthal area, 35.2% on the lower eyelid, 10.7% on the upper eyelid, and 5.6% on the lateral canthus. There was no significant difference between the left/right distribution in males and females. The average follow-up time was 34 months (standard deviation 26.38 months). A cumulative rate of no recurrence tabulated by modified life table analysis was 0.9864. Conclusion: This study further documents the problems associated with basal cell carcinoma of the periocular area as well as the value of Mohs micrographic surgery as treatment.

Mixed Tumors

Sebaceous gland tumors and other tumors exhibiting sebaceous differentiation have been described in humans (1,2,3). Tumors of the sebaceous gland can be induced in rats and mice following topical application of carcinogens (4), but spontaneous mixed tumors of basal cell origin rarely occur in mice.
