Bier`s spots present as vascular mottling, and this consists of small, irregular macules surrounded by a red to cyanotic background. The macules most commonly occur on the arms and legs of young adults, but they may also appear on the trunk. They are considered a vascular anomaly, with vasoconstriction in the pale areas and vasodilatation in the erythematous skin. Although Bier`s spots are occasionally discovered in young adults, they are still a challenge to differentiate from other hypopigmentation disorders. We report here on two cases of Bier`s spots on the extremities and trunk of 2 young adults. (Korean J Dermatol 2010;48(12):1097∼1099)

An apocrine hydrocystoma is a translucent cystic nodule that looks like adenomatous cystic proliferation of an apocrine gland, which originated from a hair germ. Dermoid cyst is a cystic teratoma that contains developmentally mature skin appendages, such as hair follicles, sweat glands, and other tissues derived from the ectoderm. Many investigators believe that dermoid cysts re originated from the ectoderm, specifically the hair germ cells. A 58-year-old woman was presented with a purple, asymptomatic, dome-shaped nodule on her right lower eyelid that had been slowly increasing in size for several years. Histopathological examination revealed two well-demarcated cysts: one was lined with stratified squamous epithelium with mature hair and sebaceous glands and the other contained large cystic spaces, which papillary projections extended. We report a rare case of a dermoid cyst, combined with an apocrine hydrocystoma, occurring in the right lower eyelid.

Erosive adenomatosis of the nipple is a rare, benign neoplasm, currently thought to originate from the terminal lactiferous ducts and subareolar breast tissue. Clinically, erosive adenomatosis of the nipple is often indistinguishable from that of mammary Paget`s disease, and it could be misdiagnosed as intraductal carcinoma as it has a similar histological finding. We present the case of a 36-year-old woman who had a unilateral erythematous induration of the nipple that contained a palpable, firm nodule. It had first been noticed 2 years earlier. The surface was occasionally crusted, and there was a bloody discharge. Histopathological examination showed irregular, dilated tubular structures, which were lined by a peripheral layer of cuboidal cells and a luminal layer of the columnar cells that demonstrated decapitation secretion at their luminal border.

Lipoma is the most common benign mesenchymal neoplasm composed of mature fat. Although lipoma can occur in any part of the body, it is infrequently found in the oral cavity. Especially, lipoma of the tongue is rare and there have been no previous reports of this in the Korean dermatology literature. Lingual lipoma, which accounts for 0.3% of all tongue neoplasm, is typically described as well-circumscribed, submucosal mass and it is located on the lateral border of the anterior two-thirds of the tongue surface. We herein report on a rare case of lipoma of the tongue that occurred in a 77-year old male patient. (Korean J Dermatol 2010;48(5):440~441)

Chronic graft-versus-host disease (GVHD) usually presents 100 days after allogenic bone marrow transplantation. Chronic GVHD cutaneous lesions are characterized by lichenoid or sclerodermoid variants. Vesicles, a common presentation in patients with acute GVHD, rarely appear in chronic GVHD. We report a case of a 49-year-old man who presented with bilateral vesicles on lower extremities. He was diagnosed with myelodysplastic syndrome 2 years before and was taking oral cyclosporine after the allogenic bone marrow transplantation. Six months post-transplantation, lichenoid and sclerodermoid lesions developed on his entire body and he was diagnosed with chronic GVHD and eosinophilic fasciitis. A biopsy of the vesicles revealed detached lower margins of the epidermis, necrotized keratinocytes, and infiltration of lymphocytic inflammatory cells. Administration of oral prednisolone alleviated the patient`s symptoms. This is an interesting case showing a new pattern of vesicle appearance after development of typical chronic GVHD lesions.
