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

Subungual Basal Cell Carcinoma: A Rare Nail Tumor with a Challenging Diagnosis

Subungual basal cell carcinoma (BCC) is a rare disorder associated with many factors, including contact with some topical and oral substances. A differential diagnosis and an early approach are important to minimize the functional damage of the limbs affected by this type of tumor. We report a case of subungual BCC in a 70-year-old woman that was managed by surgical excision. The patient's medical history included the previous use of arsenic. We emphasize the contribution of an early diagnosis to achieve better treatment results in this instance.

Periungual basal cell carcinoma

Periungual basal cell carcinoma is rare and needs to be differentiated from other common diseases that affect this region. Several factors are associated with the development of this tumor, and sun damage seems to play an important role in its pathogenesis. Dermoscopy of clinically indolent lesions on the nail unit can shorten the diagnostic process and avoid destructive treatment and functional damage.
