ABSTRACT

Grover disease (also known as transient or persistent acantholytic dermatosis) is a pruritic polymorphic papulovesicular eruption that is histologically characterized by the presence of epidermal acantholysis. It primarily occurs in middle-aged individuals and manifests as scattered erythematous or brown papules as well as papulovesicles on the sun-exposed skin of the trunk. A 52-year-old man had erythematous papules and patches linearly arranged on the left thigh and leg with mild pruritus. The skin lesions were successfully treated with a topical corticosteroid. However, 2 months later, the lesions recurred. The histological examination of a punch biopsy revealed focal acantholytic clefts with dyskeratotic cells, hyperkeratosis, and the infiltration of perivascular lymphocytes and eosinophils. Taken together with the late onset and lack of family history, we diagnosed this condition as Grover disease distributed along the Blaschko line, a condition presented here for the first time.

ABSTRACT

Folliculocystic and collagen hamartoma is a newly described complex hamartoma characterized by abundant collagen deposition, concentric perifollicular fibrosis, and keratin- filled infundibular cysts that are visible on histopathological examination. Here, we report the case of a 19-year-old Korean man who had large brownish infiltrated plaques with numerous follicular comedo-like openings and subcutaneous cystic masses on his right temporal scalp and ear since birth. Histopathological examination showed abundant collagen deposition in the dermis that extended up to the subcutaneous fat layer, multifocal infundibular cysts packed with keratin, and perifollicular inflammation and fibrosis. Hence, we describe a new type of hamartoma with folliculocystic and collagen components but without tuberous sclerosis.

ABSTRACT

BACKGROUND: Aurora kinase A (Aurora-A) plays an important role in the regulation of mitosis and cytokinesis. Dysregulated Aurora-A leads to mitotic faults and results in pathological conditions. No studies on Aurora-A expression in human diabetic skin tissue have been reported. In light of this, we explored the expression of Aurora-A in human diabetic skin tissue. METHODS: Aurora-A protein was evaluated by western blotting in 6 human diabetic skin tissue and 6 normal skin specimens. RESULTS: Increased expression of Aurora-A protein was detected in all diabetic skin tissue samples in both western blot analysis and immunohistochemical staining. However, in the case of the normal skin tissue, no bands of Aurora-A protein were detected in either the western blotting analysis or the immunohistochemical staining. CONCLUSIONS: Thus far, there have been no studies on the expression of Aurora-A in diabetic skin tissue. However, we believe that oxidative DNA damage related to the expression of Aurora-A protein and Aurora-A could be involved inhuman diabetic skin tissue.
