Disfiguring hyperpigmentation of the exposed areas may have impartant and lasting effects on the emotional well-being of the patient. And many attempts to treat areas of hyperpigmentation have been earried out, but all of them are not very successful. Recently 4-isopropylcatechol has been known to inhibit melanin pigmentation with a selective action on melanocytes either destroying or inactivating the melanocytes experimentally. There is no report on its clinical trial till now. In this study, 1% 4-isopropylcatechol cream was topieally applied to the hyperpigmented lesions of 29 patieots of melasma, freckle, and cafe-au-lait spot. The bleaching effect on meiasmas was very satisfactory in all patients but coantact dermatltis in 3 patients and reticular hyperpigmentation with areas of depigmented spots in one patient were developed as the side effects of the drug. Freckle and cafe-au-Iait spots were not bleached.

We observed 17 cases of cafe au lait spots histopathplogi ally. Out of 17 cases, 9 cases were neurofibromatosis with neurofibromas, 6 cases were neurofibromatosis without neurofibroma, and 2 cases were normal healthy persons. The results were as follows. l. In all 17 cases, melanin pigment was increased in melanocytes and keratinocytes. 2. Griant pigment granules were identified only in 3 cases of neurofibromatosis with neurofibromas.

Congenital pseudarthrosis of the tibia is a condition most often combined with cafe-au-lait spots and neurofibromatosis. It is notoriously difficult to attain a sound bony union. Compression plating and screw fixation with massive bone graft resulted in successful union in our case.

Elephantiasis neuromatosa is one of 3 types of cutaneous tumors in Von Recklinghausen's disease. This 28 year-old male patient visited for adult-fist sized tumor associated with hairy pigmented patch on right antecubital fossa, and various sized tumors and cafe-au-lait spots on whole body of about 27 years duration. Past history was noncontributory. Family history revealed that his father and son had similar manifestations. Laboratory findings were noncontributory. Histopathology of cafe-au-lait spot and hairy pigmented patch revealed increase of melain in basal cell layer of the epidermis and increase in the concentratiton and activity of the melanocytes in basal cell layer of the epidermis. Histopathology of the mass revealed slightly thin, wavy fibrs lying in loosely textured strands extending in varying directions and a fairly large number of nuclei that are ovel to spindle-shaped and fairly uniform in size.

Neurofibromatosis is characterized by multiple cutaneous neurofibromas, cafe-au-lait spots and a broad spectrum of clinical, pathologic and radiologic finding. The incidence of malignant neoplasms complicating neurofibromatosis has never been satisfactorily estabilished ; estimates range from 3% to 15%. The malignant tumors are usually derived from neural crest tissue. Gastrointestinal involvement appears to be rare and usually consists of neurofibromas, ganglioneuromas and leiomyomas. Hepatobiliary involvement in neurofibromatosis is rare and mostly located at the periampullary region. Most of theses tumors are carcinoids or less frequently neurofibromas. The authors report a case of peripheral cholangiocarcinoma associated with neurofibromatosis type 1.

We report a case of epidermal nevus syndrome showing various skin manifestations improved with CO₂ laser and chemical peeling in a 11-year-old girl. Skin lesions were composed of linear verrucous plaques and numerous papillomatous papules on the face, neck, scalp and trunk, multiple congenital nevocellular nevi on the face, and extensive cafe au lait spots on the trunk. The associated findings of skeletal involvement were gingival hemihypertrophy and benign bone lesion of the 7th rib. CO₂ laser and chemical peeling MCA, 50% TCA) were applied to remove these skin lesions which improved considerably.

Neurofibromatosis(Von Recklinghausen's disease) is an autosomal dominant disease that affects one in 2,500-3,000 births. The clinical presentation is characterized by multiple pigmented lesions of the skin, known as cafe-au-lait spots, and neurofibromas of the skin. The criteria for diagnosis are at least six cafe-au-lait spots, each greater than 1.5cm in diameter and positive family history and biopsy of a neurofibroma. Management of benign neurofibromatosis must be individualized for each patient and ranges from incisional biopsy to wide local excision. Genetic counseling is advised for all patients with this disease, since no cure is available. We report the case of multiple neurofibromatosis with oral, parapharyngeal space and whole body lesions that was treated with surgical excision.
