Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

We report a case of cutaneous focal mucinosis in a 60 year-old male, who had asymptomatic localized small flesh colored papule and nodule on the left side of the neck. The histopathologic finding revealed fibroblastic proliferatior in the dermis and an increased prodact on of hyaluronic acid by these fibroblasts. The lesions were treated by surgical excision.

We report a case of tuberculosis verrucosa cutis in a 33-year-old male patient who presented with mild itching verrucous plaque over the perineum. The Mantoux test revealed a positive reaction. The histophathologic picture consists of slight hyperkeratosis, irregular ac:anthosis overlying an inflammatory iafitrate in the dermis. Tuberculous granulomas with caseation necrosis were seen in the dermis. Tuber clebacillus was demonstrated. The patient was treated with Isoniazid, Rifampicin, and Pyrazine made for 6 months. To date, the skin lesions have markedly improved.

8.A Case of Primary Erythermalgia.

An 18-year-old man had suffered from intense burning with redness and an increased temperature of both the lower legs, forearms and hands since the age of 5. Symptoms were exacerbated by exposure to heat or walking. The patient obtained temporary relief by immersing his feet and hands in cold water. We observed the increase of skin temperature in relation to pain by thermography. No specific abnormalities were noted in laboratory studies. Treatment with aspirin was ineffective. We report a rare case of primary erythermalgia with typical features.

PURPOSE: In vitro sonography of lymph nodes was performed to ascertain the differential point between benignancy and malignancy. MATERIALS AND METHODS: Ninty-one lymph nodes were obtained at gastric cancer surgery and pathologically proved as benignancy in 68 and malignancy in 23 cases. Sohographic and pathologic correlation of resected ninty one lymph nodes was done in terms of size, the ratio of longest diameter versus shortest diameter, central hyperechogenicity, and peripheral cortical echo. RESULTS: Sonographic findings of benign lymph node were small size, oval shape(85%), narrow central high echogenicity(44%), and symmetric cortical thickening(41%). Sonographic findings of malignant lymph node were large size, round contour(39%), loss of central high echogenicity(82%), and diffuse increase of cortical thickness(82%). CONCLUSION: The most reliable sonographic criterion for differentiation of benignancy from malignancy was size of a lymphnode.
