What type of skin lesions are seen in patients with mycosis fungoides?

Although the classic skin lesions are scaly patches, plaques, and tumors, a wide variety of skin lesions have been reported, such as follicular papules and pustules with or without alopecia (alopecia mucinosa). Bullous, erythrodermic, hypopigmented, vasculitic, and hyperkeratotic lesions also have been described.

A rare variant of mycosis fungoides is granulomatous slack skin disease (Fig. 46-3). This disorder is characterized by the slow development of lax erythematous skin that eventually develops large pendulous folds of redundant integument. Histologic examination shows a dense atypical granulomatous infiltrate with destruction and phagocytosis of elastic tissue.
