Cutaneous leiomyoma is a benign dermal tumor of smooth muscle. Leiomyoma can occur at any age but typically develops during adolescence or early adult life. Congenital leiomyoma is an extremely rare reported variant. A five-month-old boy presented to our clinic with a progressively enlarging mass on his occipital scalp. Microscopic examination of the solitary ulcerated nodule showed a non-encapsulated mass in the dermis composed of spindle-shaped cells. The diagnosis was confirmed by immunohistochemical studies, which were compatible with leiomyoma. Therefore, clinical suspicion of leiomyoma should be considered in the case of a solitary ulcerated nodule in an infant.

Lymphomatoid granulomatosis, a rare lymphoproliferative disorder, was previously defined by categorical pulmonary involvement with possible invasion into the skin, central nervous system, liver, and kidneys. However, recent reports have documented confirmed cases of lymphomatoid granulomatosis without lung involvement. Here, the authors describe a 70-year-old male with rheumatoid arthritis on methotrexate who presented with an ulcerating lesion on the right lower eyelid, initially suspicious for a basal cell carcinoma.
