PURPOSE: The objective of this study was to evaluate the findings of ultrasonography (US) in patients withis-chial bursitis. MATERIALS AND METHODS: Our study included 27 patients (mean age 62 years) who underwent US fora painful mass or tenderness in the buttock area. In six of these 27, serous fluid was obtained by needleaspiration, and in five cases, bursal excision permitted histologic confirmation. The other sixteen patients werefollowed up for one or two months with only NSAID medication; all showed some improvement or remission of symptoms. Using a 5-10 MHz linear array probe, US examination was performed while the patient was lying facedown. US images were analyzed with regard to location and size of the lesions, thickness of cyst wall, thepres-ence of internal septa or mural nodules, echogenicity of the cyst wall, fluid content, internal septa,compressibility by a probe, and Doppler signals within the cyst wall. RESULTS: In all 27 patients, ischialbursitis was located superficially to ischial tuberosity. Lesion size(maximum diameter) was 1.5-7(mean 3.8)cm, andthe cyst wall was 0.2-0.8cm thick. Internal septa and mural nodules were seen in 12 cases (44%) and 13 cases(48%), respectively. The cyst wall was identifiable in 21 cases (78%), appearing as a single layer with lowechogenicity (n=10) or with high echogenicity (n=1); it also appeared as two (n=6) or three (n=4) layers ofdifferent echogenicities. When internal septa were present, fluid within the cyst was low echoic in 59% of cases,high echoic in 30%, and of mixed echogenicity (so-called compartmentalization) in 15%. In all cases, the cystbecame deformed, when compressed by a probe. In all patients who underwent doppler examination, some vascularitywas found within the cyst wall. CONCLUSION: US helped to detect ischial bursitis; US findings were thin-walled cystic lesion located superficially to ischial tuberosity, with or without internal septa and mural nodules, andeasy compressibility.

Trichoadenoma is a rare benign tumor and it appears as a solitary tumor on the face and buttock. Histologically, it is characterized by numerous horny cysts lined with stratified squamous epithelium and solid epithelial tumor nests. This tumor is less mature than trichofolliculoma and more differentiated than trichoepithelioma, and it is considered as a tumor with differentiation toward the infundibular portion of the pilosebaceous canal. A 39-year-old woman presented with asymptomatic, solitary, 1.5x1.5 cm sized, pedunculated mass on her buttock for 2 years. Histopathologic examination showed characteristic features of trichoadenoma. Trichoadenoma is so rare that only 3 cases have been reported in the Korean literature.

Sclerosing epithelioid fibrosarcoma (SEF) is a rare and poorly recognized variant of fibrosarcoma of deep soft tissue. We report the case of a 34-year-old woman who presented with a painful and palpable mass in the left buttock that was diagnosed as SEF.

We report here on a case of the giant and hyperkeratotic variant of porokeratosis. A 51-year-old man presented with a 30x20 cm sized extremely hyperkeratotic brownish verrucous plaque on his buttock. Histologic examination showed an increased number and size of the cornoid lamella, which displayed packed parakeratotic cells and the partial loss of the underlying granular layer. We diagnosed the patient with the giant and hyperkeratotic variant of porokeratosis on the basis of the clinical features and the characteristic histologic findings. Giant porokeratosis is a rare clinical condition among the several subtypes of porokeratosis, and the hyperkeratotic variant is an extremely rare clinical condition.

Adenolipoma of the skin is an unusual variant of lipoma and this is characterized by the presence of normal eccrine sweat glands within a lipoma. This morphologically distinct variant is a rare lesion with a predilection for the thigh. We report here on a case of adenolipoma and we review the relevant medical literature.

Chromhidriosis or the production of colored sweat is a rare clinical finding. Several dyes, when injected intravenously, have been shown to be secreted in eccrine gland, but in most cases the sweat is colored in skin surface, resulting from the contamination by dyes, pigment from microorganisms, or other chemicals. We report a case of eccrine chromhidriosis which revealed blue-green spots on palms, soles, buttocks, and back.
