 Abstract
 PDF
- Clear cell acanthoma (CCA) is an asymptomatic benign lesion of unknown origin that typically appears as a brownish, dome-shaped papule on the leg. It has an unusual clinical feature in that it appears as chronic eczema, Bowen disease, or Paget disease on the areola. Its histopathologic findings are well-demarcated psoriasiform acanthosis with pale keratinocytes (clear cells) that are rich in intracellular glycogen, which stain positively with Periodic acid-Shiff. We report herein on a young female patient with CCA on the areolar areas.

Abstract
PDF
- Multiple symmetric lipomatosis (MSL) is a rare disease characterized by symmetrical massive fatty deposits on the face, neck, shoulders, and upper trunk. We report a 74-year-old man who complained of painless subcutaneous nodules on his posterior neck that developed 3 weeks earlier. In a week, variably-sized similar lesions developed on both his shoulders and upper extremities. At the time of his hospital visit, several firm nodules as big as a walnut to a child's fist and with the normal-skin-hue were observed on his posterior neck, both shoulders, upper extremities, and trunk. The histological examination of his upper left arm revealed more mature adipocytes without encapsulation in the subcutaneous tissue. MSL was generally known to occur slowly over months or years. However, this is an unusual case that showed a fast-growing nature.

Abstract

- Pyogenic granuloma is one of the common benign vascular tumors of infants and children and it can also occur in adults. There are 25 reports of patients with pyogenic granuloma in the Korean medical literature. In three reports, giant pyogenic granuloma developed over 2 cm in size (1.3 x 0.7 cm, 1.2 x 0.8 cm and 1.1 x 0.7 cm, respectively). There have been no reports in the Korean medical literature of pyogenic granuloma over 2 cm in size. Herein, we report on a giant pyogenic granuloma on the palm of a 72-year old female. The lesion was of an unusually large size of 2.8 x 2.5 x 1.3 cm and we excised it by performing electrosurgery.

Abstract

- Verruca plana is caused by human papillomavirus. Clinical features are 2- to 4-mm slightly elevated, flat topped, smooth papules that may be hyperpigmented. They are generally multiple and are grouped on the face and hand dorsum. Children and young adults are primarily affected. We report a case of verruca plana with vitiligo like lesions in a 6-year-old female patient. She had been treated with topical imiquimod cream and the lesions were getting better.

Abstract

- Lichen striatus is a inflammatory disorder characterized by distinctive linear distribution of papules. The lesion presents commonly on the extremities and facial involvement has been reported as being less frequent. Only four cases have been reported in the Korean literatures. A 3-year-old patient presented with linear erythematous papules on the nose. Histopathologically, the lesion showed spongiosis in the epidermis and lymphocytic infiltration around the hair follicles and eccrine glands in the dermis. We report a case of lichen striatus with facial involvement.

Abstract

- Treatments for alopecia areata include topical corticosteroid treatment, corticosteroid intralesional injection, systemic corticosteroid treatment, PUVA(psoralen-UVA) and topical immunotherapy. The therapeutic effects are variable. Alopecia totalis is hard to treat completely. Topical immunotherapy with dinitrochlorobenzene (DNCB), squaric acid dibutyl ester (SADBE) or diphenylcyclopropenone (diphencyprone, DPCP) represents the most accepted therapeutic modality for the treatment of extensive alopecia areata. We report two cases of alopecia totalis treated with DPCP. After DPCP treatment, total scalp hair was completely recovered.

- Cases of coexistent lichen sclerosus et artrophicus and morphea have been reported. It is controversial that both diseases are single disease-spectrum or entirely separated. We encounterd a forty five year old female with a hypopigmented firm plaque on the left neck. Its histologic feature showed compact orthokeratosis, follicular plugging, atrophy of the stratum malpighii with vacuolar alteration of basal layer, and homogenization of the collagen in the upper dermis (lichen sclerosus et atrophicus). Increased thick collagen bundles were seen in the lower dermis (morphea).

- We report a case of subungual solitary glomus tumor in a 28-year-old female, who has suffered from pain and tenderness of the left 4th finger tip for about 5 years. Simple surgical excision was performed for removal of the tumor mass and for the relief of the subjective symptoms. No recurrence has been observed for 5 months following excision of the tumor.

Abstract

- We report a case of piroxicam-induced photosensitive dermatitis in a 54-year-old female. She had taken oral piroxicam and was exposed to the sunlight on her way home for a few minutes. Several hours after the sun-exposure she developed well-defined, confluent, erythematous plaques and numerous vesicobullae with pruritus and prickling sensation on the sun-exposed areas. A phototest was done on her first visit. The minimal erythemogenic dose (2 J/cm²) of ultraviolet (UV) A was markedly decreased whereas that of UVB was within a normal limit. Visible light irradiation for 30 minutes did not cause skin lesions. Six months after the initial skin lesions, a photopatch test with 1% and 10% piroxicam solution followed by UVA (10 J/cm²) irradiation showed positive responses on both concentrations.

Abstract

- A case of sporotrichosis misdiagnosed as lupus vulgaris was presented. A 56-year-old woman had been to pea sized, nontender pustules and a hypertrophic-scar-like nodule on the right thigh. She denied any trauma before the lesions developed. Histopathologic findings from the lesion showed tuberculosis-like granulomatous changes. And she was diagnosed as lupus vulgaris. She also had pulmonary tuberculosis and had been treated with antituberculous drugs for 1 year. But skin lesions was not cleared. We suspected the lesions as one of deep mycoses and could confirm sporotrichosis by mycologic studies. They showed characteristic gross colonies and microscopic findings of Sporothrix schenckii..

- Extramammary paget's disease is uncommon intraepithelial carcinoma of the skin and frequently associated with a subjacent or a regionally proximate carcinoma. We have experienced a case of extramammary Paget's disease affecting 71 year-old man. The patient has been suffered from a well demarcated, and slowly growing erythematous plaque on the left suprapubic area of 3 years. A biopsy specimen reveals infiltration of typical Paget's cells within the epidermis and the adnexa. We review the literature briefly.

Abstract

- KOH examination is a simple, rapid and diagnostic procedure to confirm dermatophytic infections. It is important to select a proper examination site of the lesion. To determinate the proper examination site of the lesion, mycologic studies were done with multiple specimens collected from the center, margin and out of margin of the ring-shaped dermatophytic skin lesion on the 58 patients. The results were as follows. Positive rate of KOH wet smear was 94.8% at the center and 100% at the margin of the lesions, 22.4% at the 1 cm and 5.2% at the 2 cm out of the lesions. The more hyphae were found in the lesion, the more hyphae were found out of the lesion. Culture was done on the Sabouraud's glucose agar from the highest KOH positive area and the positive culture was 48 strains (82.8%) of 58 patients. These findings suggested that the ring-shaped active margin was the best site to examine mycologic studies.
