TLDR A rare scalp tumor involving two hair follicles was successfully removed with surgery, with no recurrence after 7 months.
Warty dyskeratoma (WD) was a rare epidermal tumor typically presenting as a solitary papule or nodule on the head or neck of middle-aged or older individuals, often involving a single hair follicle. This case report described a unique instance of WD involving two adjoining hair follicles in a 47-year-old man with a 4 to 5-year history of a scalp nodule. Histological examination revealed two large cup-shaped invaginations filled with keratinous material, with typical features of WD such as suprabasal clefts and acantholytic dyskeratotic cells. The lesion was successfully treated with excisional biopsy, with no recurrence observed during a 7-month follow-up. The etiology of WD remained unclear, though factors like viral infection and ultraviolet light were considered. Surgical excision was the preferred treatment, with other methods like curettement and electro-desiccation leading to recurrence.
