Adenoid cystic carcinoma is known to be a neoplasm of the major and minor salivary glands but it also occurs in the lacrimal gland, external auditory canal, easphagus, breast and skin. Adenoid cystic carcinoma of salivary gland is a slow-growin nalignant tumor. Although metastasis of this tumor clevelnps in about half the cases, its meta taes to the overlying skin is not common, moreover the skin metastasis to the remote site is raely found. Primary cutaneous adenoid cystic carcinoma is rare and histologically indistingisl able from skin metastasis of adenoid cystic carcinoma of the salivary gland. A 53 year-old man presented a solitary, well defined, erythen at us, 1.3 x 1.3cm sized nodule on the vertex of the scalp, which revealed the typical histopatholog ndings of adenoid cystic carcinoma. One and half years ago, a tumor of the parotid gland va removed and proved to be a cribriform pattern of adenoid cystic carcinoma. The skin lesion was diaghosed as a skin metastasis of the alenoid cystic carcinoma of parotid gland rather than a primary cutaneous adenoid cystic carcinona because a similar pattern of adenoid cystic carcinorom had been discovered on the parotidg an l although it developed on the scalp, the usual site of primary cutaneous adenoid cystic carcinama.

Intravascular papillary endotholial hyperplasia is a relatively rare (istose which is characterized by the development of endothelialdined papillary projections in a vascula humen. It is commonly found to be associated with thromboticrraterial and is now considered a reative process of the endothelium rather than a neoplastic one. Although this disease usually presents petri dish or bluish nodule on the head, neck or upper extremiti it can develop anywhere on the bod, . There are many reports about lesions in unusal locations, but t.hey are almost always solitary. A 61-year-old woman complained of multiple, tender, 1 x 1 to 4 x 5 creasized nodules on both hands, antecubital fossa, chest, abdomen, left shoulder and right calf. These the nodules showed reddish to bluish colors and had long hisbiries from 1 year to 7 years. Four our 13 lesions were excised for histopathologic diagnosis intravascular papillary endothelial hyperplaian 3 lesions and cavernous hemangioma in 1 lesion.(

Hypergammaglobulinemic purpura of Waldenstrom is a distinct syndrome consisting of recurrent episodes of purpura, elevated serum r-globulins, elevated erythrocyteed rnentation rate, and mild anemia. This disease has been divided into the prirnary type without an uncerlying disease, and the secondary type with a known underlying disease. We diagnosed a hypergammaglobulinemic purpura of Waldenstram in a 53-year-old woman who presented sudden onset of showers of purpuric macules and petechiae of 24 hours duration involving her lower extremities with a 10-rnonth history. She showed characteristic laboratory findings consistent with those of hypergammiglobulnemic purpura of Waldenstrorri and also showed positive results of antinuclear antibody and rheumatoid factor. We tried to find out if there we any associated underlying disases such as systemic lupus erythematosus or Sjogren synirorne through various tests but faile it find any. We concluded she showed a primary type of hypergarnmhglobulinemic purpura of Waldcnstrorn.

Higt energy electron beam therapy is a method which is used for the treatment of superficial tumors (less than 5 cm deep) with a characteristically sharp drop-off in dose beyond the tumor. This method offers distinct advantages in dose uniformity and in minimizing the dose to deeper tissues. We report herein three cases of epithelial skin cancer treated with high energy electron beam. The first patient was a 79-year-old male who had primary basal cell carcinoma(BCC) on the right lateral canthus. The second patient was a 67-year-old male who had recurreiit BCC on the right cheek. Both of them received electron beam therapy on the lesion and there were no clinical relapse signs over 1 year. The third patient was a 46-year-old male who had squamous cells, carcinoma on the lower lip. He also received electron beam therapy on the lesion, but it recurred.

Angioma serpiginosum is a rare vascular naevoid disorder due to progressive ectatic dilatation of capillaries in the papillary dermis. We report two cases of angioma serpiginosum. A 24-year-old woman presented with asymptomatic multiple deeply red macules arranged in a serpiginous pattern on the left posterior thigh. In the other case, an 8-year-old girl had asymptomatic red nonpalpable puncta that were grouped closely together in a linear pattern from the left lower abdomen to thigh. On the histopathological examination, both cases commonly showed grouped, dilated, ectatic vessels in the upper dermis. These clinical and histopathological findings were typical of angioma serpiginosum.

BACKGROUND: It is well-known that the giant congenital nevi prcgress to malignant, melanama more frequently than other benign melanocytic nevi but to date the laor tory methods for early detection of such progression were not avsilable. The proliferating cell uncleai antigen(PCNA) staining has been regsrded as an useful marker in determining prognosis of some maignant diseases. OBJECTIVE: The PCNA taining was performed as a predictive value of malignant transformation from benign meanocytic skin lesions. We investigated the differcnces between malignant melanoma and the benign lesions. MATERIAL AND METHODS: Immunohistochemical study was employee using anti-PCNA, anti-S-100, and anti-CD45RO antibody in 6 giant congenital nevi, 8 small and medium sized congenital nevi, 10 acquired nevi, and 10 malignant meanomas. Only cells positive for both PCNA and S-100, and negative for CD45RO on the serial sections were identified as melanocyts. RESULTS: The number of PCNA-posit,ive cells per 1000 melanocy,es averaged 6.0+7.5 in giant, congenital nevi, 2.9+1,9 in small and medium sized congenital novi, 3.1+2.7 in acquired nevi, and 61.5+ 39.4 in malignant, melanomas. Malignant melanomas showed onger intensity of PCNA staining than the other melanocytir nevi. CONCLUSION: There was not significant difference of the numter of PCNA-positive cells among the groups of congenital neviind PCNA staining can't be used in prditive measure of malignant. progression and studying mechansm of malignancy in giant congenital nevi. But, PCNA staining is considered as an useful method in differentiat,ing malignant melanoma from mllanocytic nevi.

The papillary eccrine adenoma is a rare benign sweat gland neoplasm charscterized by potentislly locally aggressive clinical course. We report herein a case of papillsry eccrine adenoma in a 28-year-old female who presented single intradermal tumor on the right postauricular ares. Histopathological findings showed dilated ducts containing eosinophilic or keratinous materials and intraluminal papillary rowths.

The pubic louse, Pthirus pubis is a blood-sucking ectoparasite adapted to hold onto pubic, axillary and body hairs. It is usually confined to the pubic and inguinal region. However, it may also rarely involve the scalp and eyelashes. We report two cases of phthiriasis occurring on unusual sites, the first case occurring on the scalp of a 5 month-old male infant, and the second case on the eyelashes of a 49-year-old fe-male.

Trichoblastic fibroma is a rare benign tumor of hair germ with mixed epithelial-mesenchymal components. A 64-year-old female presented with an asymptomatic, skin-colored, firm nodule on the left knee joint. Histopathologic examination showed multiple tumor islands and strands eomposed of basaloids cells embedded in a moderately cellular fibroblastic stroma and the for vation of bud-like extension of tumor cell nest. The peripherel basaloid cells shovred a palisading arrangement and small keratinous cysts were formed in tumor islands.
