Annular elastolytic giant cell granuloma is a rare form of granulomatous dermatosis, characterized clinically by annular plaques with slightly elevated margins, and histopathologically by the phagocytosis of elastic fibers by multinucleated giant cells. It typically occurs in sun-exposed areas of the skin in middle-aged women. However, some cases involving unexposed areas have been described. A 57-year-old man had erythematous plaques on both palms accompanied by a sensation of heat for 2 weeks. Histopathological examination revealed granulomatous infiltration with multinucleated giant cells and elastophagocytosis, which is consistent with annular elastolytic giant cell granuloma. Herein we report an interesting case of annular elastolytic giant cell granuloma that occurred on non-sun-exposed skin, palms.

Grover disease (GD), also referred to as transient or persistent acantholytic dermatosis, is an acquired pruritic papular or papulovesicular eruption characterized histopathologically by focal acantholysis and dyskeratosis. Because GD resembles several generalized papular diseases, the diagnosis of GD is a clinical challenge, particularly when dermatologists meet patients without papular eruptions. We experienced two elderly men showing eczematoid plaques with severe pruritus on their backs. Histopathological examinations revealed a focal acantholysis, spongiosis, and dyskeratosis, a pattern consistent with GD. We report two cases of GD with clinical features of nonspecific eczematous dermatosis.

Squamous cell carcinoma of the nail apparatus is a rare phenomenon. Because of its indolent course and similar presentation to other benign conditions, correct diagnosis in the early stages is practically difficult. We here report two cases of periungual squamous cell carcinoma and squamous cell carcinoma in situ (Bowen's disease). These cases emphasize the importance of extra vigilance and high suspicion when facing intractable atypical lesions on the fingers. Repetitive biopsy with exploratory nail plate extraction should be considered to acquire appropriate specimens, which is critical for early and correct diagnosis.
