Among 13 patients with pemphigus : 8 of pemphigus vulgaris(PV), 4 of pemphigus foliaceus(PF), l of pemphigus erythematosus(PE), we have examined the sites of early lesions and the clinical appearances of the skin lesions. The most common site of the early lesions in PV was the oral mucosa, however, in PF and PE the face was affected first. The clinical appearances of the early lesions were flaccid bullae, erythematous papules and eczematoid patches. Clinicians should be aware of these clinical features of pemphigus for a more precise diagnosis and better management.

Trichoadenoma is a rare cutaneous tumor that was first described by Nikolowski in 1958. It usually occurs as a single tumor on the face and its size varies from 3 to 50mm in diameter. It may arise any time during adult life. This tumor is less mature than trichofolliculoma and more differentiated than trichoepithelioma, and it is considered as a benign tumor with differentiation toward the infundibular portion of the pilosebaceous canal. In this report, we describe a 61-year-old women who developed trichoadenoma on the left shoulder of 3 years duration. The lesion was asymptomatic and had grown slowly. Histopathological findings showed numurous horn cysts with central keratinous material and solid tumor islands reaching to the deep dermis. Immunohistochemical studies showed negative findings for eccrine differentiation. (Korean J Dermatol 1998;36(2) . 372-375)

Most insects including the honeybee cause erythema and edema at the site of a sting in non-allergic individuals. This reaction usually resolves within a few days. However, in certain cases, the persistence of inciting materials in the cutaneous tissue may promote a local inflammatory foreign body reaction. Localized nodular lesions were seen in our two patients and erythemstous patches were present in one patient due to rarely encountered complications induced by retained sting materials. In these cases histopathology showed multiple foci of foreign body granuloma containing yellow refraetile material in the center surrounded by histiocytes and foreign body giant cells. The granulomatous skin lesions in these patients were treated with intralesional injections of triamcinolone acetonide and partial excisions of the nodular masses were performed (Korean J Dermatol 1998;36(5): 914-917)

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.
