A 78-year-old man with myelodysplastic syndrome presented with multiple asymptomatic indurated nodules localized to the submental region. There were accompanying recurrent and episodic fevers (temperatures, >38°C). He denied any other symptoms and reported no history of trauma to the area. Physical examination revealed multiple nontender, small, well-demarcated, nodular erythematous to violaceous cutaneous lesions spanning the submental region. An excisional biopsy of the skin and subcutaneous tissue was performed in the operating room.
