A Case of Zosteriform Kaposi's Sarcoma / 대한피부과학회지

Kaposi's sarcoma is a neoplastic, vascular tumor involving the skin or internal organs. We report a case of a 72-year-old male who presented with multiple, grouped, purpuric papules, hemorrhagic bullae and nodules showing zosteriform distribution on the sole of his right foot. In our case, as in some of the cases from the literature, the patient was initially misdiagnosed clinically as having herpes zoster. Histopathologic findings revealed a diffuse infiltrate of small blood vessels and slit-like spaces extending through most of the dermis. Many of the spindle-shaped cells expressed factor VIII-related antigen, and human herpes virus 8 (HHV-8) DNA was detected by polymerase chain reaction (PCR) in paraffin-embedded tissue.

A Case of Multiple Eccrine Spiradenoma with Zosteriform Distribution / 대한피부과학회지

Eccrine spiradenoma is a benign tumor which probably originats in the coil of the eccrine sweat gland. It usually presents as a solitary, slowly-growing, sometimes painful, reddish-brown, and intradermal or deeply subcutaneous nodule on the head and trunk. More than 97% of eccrine spiradenoma appear as solitary lesions. Occasionally, it may appear as multiple lesions, however they are rarely arranged in a linear or zosteriform distribution. A search of literature revealed only 17 internationally reported cases of linear or zosteriform eccrine spiradenomas, including 4 Korean cases. We herein present an unusual case of eccrine spiradenoma, showing multiple, large nodules with zosteriform distribution.

A Case of Multiple Eccrine Spiradenomas with Zosteriform Distribution / 대한피부과학회지

Eccrine spiradenoma is clinically characterized by a slowly growing, deep-seated nodule occurring most frequently on the ventral surface of the body. It is solitary in 95% of cases. Rarely, multiple lesions may be present and may occur in a linear or zosteriform pattern. Until now only two cases of eccrine spiradenoma in zosteriform pattern have been reported in Korean literatures. A 19-year-old male presented with multiple, gray, macular lesions in a zosteriform distribution along his left subscapular area. These 10-years-old lesions gave him occasional paroxysmal pain. Two years later, the lesions became palpable in the subcutis and were diagnosed as eccrine spiradenoma by an excision biopsy. During the 4 years thereafter, the remaining lesions grew slightly and became symptomatic, which resulted in a second surgical removal. We report a rare case of multiple eccrine spiradenomas with zosteriform distribution with observation of 6 years course.

A Case of Zosteriform Cutaneous Metastasis / 대한피부과학회지

We report a case of zosteriform cutaneous metastasis from lung cancer in a 72- year-old male patient who have asymptomatic confluent or discrete hard papulonodules over the right upper arm and right side of chest. Histopathologic examinations of the cutaneous lesion revealed neoplastic cell, which showing glandular structure, infiltrating in the drmis and subcutaneous layer. Also histopathologic findings of metastatic lesion of skull and olecranon are similar to them. Fie died after three months from the appearance of cutaneous metastasis

Lichen Sclerosus et Atrophicus

A 48-year-old male patient had white to ivory colored patches on brown colored bases over the right side of his back for 8 years without accompanying pruritus or pain. Six months prior to the onset of his skin eruption, he received acupuncture for the relief of right sided back pain for 1 month. Histopathologic examination of the white patches showed follicular plugging, epidermal atrophy, focal hydropic degeneration of basal cells, lymphedema of papillary dermis, thickened homogenization of collagen fibers; consistent with findings previously reported in lichen sclerosus et atrophicus. We report this case to document the occurence in an acupuncture site and stress the unusual clinical manifestation of a zosteriform distribution.

A Case of Premature Sebaceous Gland Hyperplasia with Zosteriform Distribution / 대한피부과학회지

We experienced an atypical case of sebaceous gland hyperplssis in a 28-year old male. He had asymptomatic, multiple, globoid, yellowish papules in a zosteriform distribution on the right lower abdomen (T8 dermatome) that were of 5 years duration. Histologically, there are many hyperplastic lobules of sebaceous glands, some of which are connected with a central dilated duct.
