Twenty six individuals with tattoos, who were seen during physical examination for conscription from Febrary to May, 1985, were biopsied for a histopatholigical study of tattoos. The results were as follows ; 1. There was perivascular deposition of pigment in all cases. 2. There cases showed deposition only in the upper dermis. 3. Six cases showed deposition in the upper and lower dermis. 4. Five cases showed deposition around the eccrine glands and two around the sebaceous glands. 5. Six cases showed mild lymphohistiocytic infiltrations in the dermis. 6. There was no difference in size of the particles regardless of infiltrated areas and tattoo materials.

Proliferating trichilemmal cyst(PTC) is a rare benign neoplasm that is thought to be derived from the outer root sheath of anagen hair follicles differentiating toward the infundibular and matrical segments, sebaceous glands, apocrine glands, or acrosyringium. Clinically, it presents as a solitary elevated, lobulated mass on the scalp of elderly women. Histologically, it shows well demarcated multiple lobules of squamous epithelium. The center of the lobule undergoes abrupt keratinization without formation of keratohyalin and foci of calcification are often present in the areas of amorphous keratin. PTC can be associated with sebaceous nevus of Jadassohn, ectopic apocrine sweat glands, spindle cell carcinoma, etc. We report an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman.

We experienced an atypical case of sebaceous gland hyperplssis in a 28-year old male. He had asymptomatic, multiple, globoid, yellowish papules in a zosteriform distribution on the right lower abdomen (T8 dermatome) that were of 5 years duration. Histologically, there are many hyperplastic lobules of sebaceous glands, some of which are connected with a central dilated duct.

There is not always a sharp distinction among the sebaceous neoplasms including sebaceous adenoma, sebaceoma, and sebaceous carcinoma. Sebaceous carcinoma is a malignant tumor derived from the adnxal epithelium of sebaceous glands. It may exhibit a variety of histological growth patterns and diverse clinical presentations. Herein we report a 65-year-old man presenting with a 0.5cm skin-colored papule on the left cheek, which shows the histopathological features of well-differentiated sebaceous carcinoma.

Acne vulgaris is a self-limited disease, seen primarily in adolescents. Most cases of acne are pleomorphic, presenting various lesions consisting of comedones, pustules, and nodules. Although it has been traditionally classified as a disease of the sebaceous gland, it actually involves the pilosebaceous unit. There are four major principles in the treatment of acne: (1) correct the altered pattern of follicular keratinization; (2) decrease the sebaceous gland activity; (3) decrease the follicular bacterial population; and (4) produce anti-inflammatory effect. The natural course of acne varies greatly, and therefore, the determination of the therapeutic efficacy of medications for the treatment of acne is far from being simple.

Sebaceous hyperplasia is not a rare disorder and commonly develops on the face over the age of forty. The typical clinical manifestations are 2 ~ 3mm sized, single or multiple, soft protuberant yellowish nodules with central umbilication and histology shows a group of mature sebaceous lobules and central sebaceous ducts. We report an exceptionally "giant" size of sebaceous gland hyperplasia which lead us to such clinical impressions as an acrochordon, intradermal nevus, and verruca vulgaris. Histologically, the lesion showed a greatly enlarged sebaceous gland composed of numerous lobules grouped around a wide sebaceous duct. Besides the extraordinarily large size of the nodule, the benign proliferating pattern led us to a diagnosis of giant sebaceous hyperplasia.
