Basal Cell Carcinoma of the Dorsal Foot: An Update and Comprehensive Review of the Literature

BACKGROUND

Ultraviolet radiation is a well-known risk factor for basal cell carcinoma (BCC). Therefore, the high incidence of BCCs in sun-exposed areas such as the head and neck is unsurprising. However, unexpectedly, BCCs on the sun-protected dorsal foot have also been reported, and tumor occurrence here suggests that other factors besides ultraviolet radiation may play a role in BCC pathogenesis. Because only few dorsal foot BCCs have been reported, data on their clinical features and management are limited.

OBJECTIVE

To perform an updated review of the literature on clinical characteristics and treatment of dorsal foot BCCs.

METHODS

We conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal foot," "basal cell carcinoma foot," and "basal cell carcinoma toe."

RESULTS

We identified 20 cases of dorsal foot BCCs in the literature, 17 of which had sufficient data for analysis. Only 1 case was treated with Mohs micrographic surgery. We present 8 additional cases of dorsal foot BCCs treated with Mohs micrographic surgery.

CONCLUSION

Basal cell carcinomas on the dorsal foot are rare, and potential risk factors include Caucasian descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment option.

Periungual Basal cell carcinoma: a case report with review of literature

Basal cell carcinomas (BCCs) are considered to be uncommon around the nail plate. An indolent lesion of this region should arouse suspicion of potential malignancy and a skin biopsy should be undertaken without delay. Early diagnosis can enable the physician to render simpler nondestructive modalities of treatment. In this article, we describe such a case of longstanding BCC of this region mimicking a traumatic ulcer. The nature of the ailment was finally discovered on biopsy and the carcinoma was initially treated with topical Imiquimod.

[Basal-cell carcinoma of fingers: a rare location not to be ignored]

The basal-cell carcinoma is the most frequent malignant tumor in human, usually involving the healthy sun-exposed skin of head and neck area, but thoracic and members localisations are possible. Macroscopic appearance is variable excepting the pathognomonic pearl. Periungual lesions are in this context very rare and we report the case of a 64-year-old man presenting with a basal-cell carcinoma on the thumb. A literature review was also performed and our purpose is to warn our colleagues about this quite often unrecognized pathology which may need a more aggressive treatment in case of delayed diagnosis, and to remind them that all chronic lesions impose a biopsy.
