BACKGROUND: The incidence of scabies in Korea decreased during the past 20 years. This might have been due to improved personal hygiene and public sanitation. Recently, however, not only the incidence of scabies, but also delayed or missed diagnosis, is likely to increase again. OBJECTIVE: This study was conducted to obtain a better understanding of the clinical characteristics of recent scabietic patients. METHODS: We reviewed the medical records and clinical photographs of 27 outpatients who had been diagnosed with scabies in our department between August 2006 and August 2008. We investigated personal and clinical information, including age, sex, onset, past history and clinical manifestations. RESULTS: Of the 27 patients, 14 (51.9%) were female and 13 (48.1%) were male. Their ages ranged from 4 to 93 years (mean=47.2 years). Over half (51.9%) of the patients had been misdiagnosed at private hospitals. The average time from symptom presentation to diagnosis was 68 days. The most common site of skin lesions was the lower abdomen (77.8%), and the most common primary lesion was erythematous papules (96.3%). Atypical cases of scabies were as follows: 7 nodular scabies (25.9%), 1 crusted scabies (3.7%) and 4 scabies incognito (14.8%). CONCLUSION: Currently, atypical cases of scabies may be increasing and frequently misdiagnosed. We suggest that dermatologists should suspect scabies for any patient who presents with pruritus that is persistent or resistant to treatment.

Cystic lymphangioma is a true, benign, congenital multicystic tumor arising from sequestrations of embryonic lymphatic tissue. Most often it occurs at birth or during the early years of life, is found most commonly in the neck, and its distribution coincides with that of the primitive lymph sacs. A 23-year-woman presented with a soft palpable mass on her chest wall. Physical and ultrasound examination revealed a well-circumscribed, mobile, nontender, soft subcutaneous mass on the right posterior chest wall beneath the latissimus dorsi muscle. A skin biopsy of the mass showed endothelium-lined lymphatic vessels and a loose, lace-like fibrous tissue stroma. The specimen was stained with D2-40 showing positive staining of lymphatics. These histopathological findings confirmed the diagnosis of a cystic lymphangioma. We report a rare case of a cystic lymphangioma on the chest wall in a 23-year-old woman.

Seborrheic keratosis is a common benign epidermal tumor histologically composed of basaloid and squamous cells. It mainly occurs on the face, scalp, and trunk, and presents clinically as a well-circumscribed, brownish to black papule, nodule, or plaque. Trichoblastoma is a relatively rare benign, slow-growing tumor showing differentiation toward the primitive hair follicle. It clinically manifests as a solitary, skin to erythematous colored, well-circumscribed dermal nodule located predominantly on the head and neck with a predilection for the scalp. Histologically, a well-demarcated mass of follicular germinative cells that show various degrees of differentiation, arranged in lobules, sheets, and nests, is located in the dermis or subcutaneous fat layer. We report the case of a 28-year-old female patient with a solitary, 2.0x4.0-cm black plaque with a 0.7-cm skin-colored nodule on the scalp. Histologically, the entire black plaque had prominent hyperkeratosis, acanthosis, and papillomatosis with horn cysts. The central nodule showed well-circumscribed, various-sized dermal tumor lobules without a connection to the overlying epidermis. The lobular aggregation was composed of numerous basaloid epithelial nests and multiple primitive papillary structures with distinct peripheral palisading of nuclei. According to these findings, the scalp lesion was diagnosed as a composite tumor associating trichoblastoma and seborrheic keratosis.

Chondroid syringoma is an uncommon, benign and adnexal tumor which is composed of a mixture of epithelial cells and mesenchymal tissue. The usual presentation is of an asymptomatic, slowly growing mass, typically located in the head and neck region. We report a case of chondroid syringoma located in the right heel of a 46-year-old male patient. The tumor grew over a 10-year period, increasing rapidly in size over the last few months. It was a skin colored, 4.5x5x4 cm-sized, hyperkeratotic hard pedunculated nodule. The diagnosis of giant chondroid syringoma was made by clinical and histopathological examination, which showed a tubular structure and solid nest composed by more than two layers of epithelial cells embedded in a myxoid-adipoid tissue. The tubular lumina contained small amounts of amorphous, eosinophilic material. Regarding previous reports, this is a quite rare case of benign chondroid syringoma due to it's unusually large size and rare location.
