A 28-year-old woman had a 13-month history of skin-colored, well-circumscribed, hyperkeratotic plaques on both heels. Histological examination showed hyperkeratosis and acanthosis in the epidermis. Special stain for elastic tissue revealed marked fragmentation, diminution and thickening of elastic fibers in the dermis. We report a rare case with the lesions of acrokeratoelastoidosis on both heels.

Myeloid body formation is an ultrastructural feature of gentamicin induced nephrotoxicity in human being and experimental animals. The origin of the myeloid body is not satisfactorily understood and morphological verification of the developing process of this structure is not fully accomplished. We injected 100 mg/kg/12 hour of gentamicin in 20 Spraque-Dawley rats and examined the ultrastructural feature of the proximal convoluted tubular cells of the kidney every 30 minutes in the first 4 hours, and in 5 hours, 6 hours, 12 hours, 24 hours and 48 hours after injection of gentamicin, with a TEM and a SEM. Myeloid bodies were noted as concentric layers of membranous structures of degenerated endoplasmic reticulum and mitochondria in the lysosome. The number and size of the myeloid body containing lysosomes were increased with time. We can deduce from this observation that injured cell organelles by diffusible gentamicin within the cells are autophagocytosed by lysosomes which were also injured by the drug from pinocytotic vesicles, and incompletely digested organellar remnants are retained in the lysosomes as myeloid bodies. So we think that the myeloid body formation is a result of an exaggerated and a pathologic autophagocytic process due to cell injury induced by gentamicin.

The surgical construction of vagina could certainlty be done by skin grafting or flaps, but it involves hospitalization, discomfort,scarring of donor area and vaginal tract, hygiene problem. The tissues of the vagina are soft and distensible and it is reasonable to assume that these same tissues could be stretched, elongated or dilated with gradual external pressure. So, we performed the expansion of vaginal lining by self designed set of graduated dilators. The patients was a 27-years-old female whose chief complaint is amenorrhea and incapability to engage in sexual intercourse. On physical examination, this patients had a feminine figure with a normal vulva but only a vaginal dimple was observed. The patient was educated to carry out the mechanical dilation of this dimply by pressure 15 minutes twice a day. In the evening, with insertion of a dilator, the patient was asked to sit on a bicycle chair for 10 minutes. After 8 weeks, the overall outcome of vaginoplasty was successful. The vaginal tract was 8 cm in length and the largest vaginal speculum could be passed into vagina. The patient was able to engage in sexual intercourse without lubrication. The progressive dilatation of vaginal lining is non-invasive and probably the simplest way to treat the patients with congential vaginal atresia. So we recommend this method as the first treatment strategy before surgery.

A 12-year-old boy developed cholestatic hepatitis with Steven-Johnson syndrome following the use of amoxicillin. The skin lesion and general condition were improved over 2 weeks, but jaundice was gradually aggrevated. We performed liver biopsy, on 30th hospital day, which showed cholestatic hepatitis. The patient improved gradually and liver function was normalized 5 months later.

Cholangiocarcinomas have several histologic types, but intrahepatic cholangiocarcinoma with sarcomatous change is rare. A 71-year-old man was admitted to our hospital because of fever which had lasted two months. Ultrasonography (US) of the upper abdomen demonstrated a huge hepatic mass with central solid and peripheral cystic portions, and computed tomography (CT) revealed a heterogeneous hepatic mass with a central area in which enhancedment was delayed. Magnetic resonance imaging (MRI) disclosed a huge mass of predominantly low signal intensity at T1WI, and peripheral portions of high signal intensity and a central portion of intermediate signal intensity at T2WI. The pathologic diagnosis was cholangiocarcinoma with sarcomatous change.

A healthy 18-year-old woman presented with an asymptomatic tiny papular eruption on the hands, forearms, legs and trunk. A skin biopsy from the left forearm revealed a typical lichen nitidus lesion associated with an adjacent transepidermal perforating lesion. We report a case of perforating lichen nitidus, and briefly review the relevant literature of perforating lichen nitidus.
