Urticaria pigmentosa is a manifestation of mastocytosis characterized by persistent pigmented cutaneous lesions of various size that tend to urticate upon mechanical or chemical irritation, The disease is most common in ehildren and skin lesions after appear within 1 or 2 months of birth. Urticaria pigmentosa in children begins with disseminated eruption (buIlou type) or with a solitary tumor or nodule(solitary type). One case. of solitary type and one case of bullous type are reported in this paper. The one case is a solitary type of urticaria pigmentosa in 1 1/2 years old male who had dark brownish pigmented nodule(2.5 1cm) on right hack since 1 year ago. Tie other is a bullous type of urticaria pigmentousa in 6 months old male who had generalizcd. bulla, hemorragic bulla with crust & millium since 4 months ago. Dignosis was confirmed by histologic findings in which showed infiltration of mast cells in upper nr entire dermis arui rnetachromatic granules in mast cell on toluidine blue stain. Literature were reviewed briefly.

Epidermolysis bullosa dystrophica is a rare, chronic non-infIammatory mechanobullous disease of hereditsry trait, which easily produces bulla by minor injury or spontaneously. Bullae usually developed first at birth or in infancy, involving especially hands, feet, knees, elbows and other pressure sites, which heal with atrophic and hypertrophic scars, loss of hair and nails, digital fusion, flexural contractures of the knee, elbow and wrist joints. A 5-year-old boy has had various sized recurrent buIlae on hands, feet, kneces and elbows, healed with atrophy of skin, miliums, deformities of toe and finger nails. Diagnosis was confirmed by clinical features and electronmicroscopic findings. Literature were reviewed briefly.

Cutaneous leishmaniasis (oriental sore) is usually a self-limited infection of the skin caused by the protozoan Leishmania tropica. The disease is endemic to the Mediterranean, Asia, Africa, and the Middle East. It has been seen in this country among many Korean technical experts and labourers working in the endemic areas of the disease. Our patient had acquired cutaneous leishmaniasis in Saudi Arabia and it had remained active for six months. He had been treated with antimony and metronidazole but failed because of severe side effects. And then we treated the patient witb cryosurgery and the skin lesions were followed by resolution with cosmetically acceptable scar in 4 months. The brief review of literature on the treatment of cutaneous leishmaniasis was undertaken.

In the present study soap chamber test was carried out for assessing irritancy of toilet soaps and soap ingredients. The results obtained in the present study are summarized as follows; This chamber test can discriminate the differences of irritancies between various soaps and soap ingredients. 2. Soap irritancy is not directly related with its alkalinity. 3, Erythema score and scaling score tend to parallel each other with weak correlation(r=p 46), but erythema score and fissuring score show strong correlation (r=p77) Scaling score and fissuring score show moderate correlation(r=p.64), 4. In the eighteen kinds of toilet soaps, two soaps are most irritating, harsh soap and the total irritancy scores of all soaps are within 1. 9 5. 1. Baby soaps are not milder than the common toilet soaps. 5. Generally, total irritancy score of soap ingredients is concentration dependent. Average total irritancy scores of five main soap ingredients in 4 times of recommended allergen concentration are as follows; Builders 5. 30, Perfumes l. 88, Color 0. 70, Fatty acids p. 35 and Superfat p.

Linear porokeratosis is a rare variant of porokeratosis and usually occurs in childhood. A 37-year-old female is presented with linear porokeratosis on the posterior aspeet of the right lower extremity exhibiting the classical histopathologic criteria of the disease. Treatment with an oral etretinate resulted in a remission of the lesions.

Purpura fulminans (gangrenosa) is a rare clinical syndrome characterized by sudden appearance of rapidly progressive symmetrical subcutaneous ecchymosis durimg the convalescent stage of various infectious disease. A 4 year-old. boy has developed multiple skin defects with necrosis on extrernities and gangrenous changes on the left foot following a meningococcemia. B-K amputation on left leg and. free skin graft for multiple skin defect on extremities were, carried out.

We observed the clinical and histopathologic characteristics of acquired, bilateral nevus of Ota-like macules in each 80 and 23 patients. The results were as follows: 1. All patients were female and the peak age of onset was third decade with an a,verage age of 27.4 years. 2. The colors of lesions were slate, brown, dark brown, and blue black in order of freguency. 3. The lesions were most comrnonly observed in the malar area and alae nasi. 4. Three patients had family history of acquired, bilateral nevus of Ota-like :macules. 5. Histopathologically pigment-bearing cells, bipolar or irregular in shape, were found mostly in the upper- and mid-portion of the dermis. The melanocytes showed weakly positive dopa reaction. 6. In electron microscopic observation, these pigrnent-bearing cells contained many singly dispersed melanosomes in stage 3 and 4 of melanization and wece surrounded by an extracellular sheath.

Friction melanosis is frequently developed in thin, young woman, on thc covered skin of spinc, rib, elbow, knee and tibia. These lesions range from brown to rcddish-brown in color, appear in either band shapes or reticular patterns, and exhibit no overt syrnptoms. They do not show any inflamatory changes, and the skin remains smooth. According to histopathological findings, the main changcs arc perivascular melanophages on the papillary derrnis and upper dermis, and also increased melanin granules on the basal layer. The following case concern a relatively thin 20-year-o1d female patient. She had a syrwptoniless brown color changcs above the ribs of back, growing in dircction of the ribs for a period of three years. This change was band shaped, but there were no signs of inflammatory reaction, leaving the skin smooth. A biopsy was performed on the relevant tissue, and clinical-histopathological analysis was resulting in diagnosis of friction melanosis.

A case of "Follicular Occlusion Triad" associated with acne conglobata, hidradenitis suppurativa and perifolliculitis capitis abscedens et suffodiens in 40-year-old male patient is presented with brief review of literature. Widespread acne occured on the face k upper back at the age of 16. Several years later, firm & tender erythematous poorly demarcated nodules developed on the back, buttock and axilla. Also, erythematous nodules developed on temporooccipital area of the scalp. Thereafter, the skin lesions become fluctuant cystic. Some of the skin lesions healed leaving severe hypertrophic scars, and purulent materials expressed from some of persistent lesions. The patient was trested with systemic 13-cis-retinoic acid, antibiotics, corticosteroids injection and incision & drainage with considerable improvement.
