    We examined the number of colonies of dermatophytes isolated from foot-press method samples. The samples were obtained from a volunteer after she stepped not only on bath mats but also on wood floors, Japanese style mattings, concrete floors, slippers, cushions, and other things that a patient with tinea pedis had previously stepped on. After she wiped with wet towels, these dermatophytes decreased to the level of 0–39.7%. We also examined a few colonies of dermatophytes isolated from finger-sampling method samples. These samples were obtained from volunteers after they stepped on bath mats that a patient with tinea pedis had previously stepped on. In the finger-sampling method, the examiner’s fingertip rubs the patient’s toe webs and immediately press on a culture dish. We hypothesized that the dermatophytes adhered to the toe webs could cause tinea pedis.

    In recent years, interventional radiology (IVR) using a intravascular catheter with X-ray fluoroscopy has become commonly used. and it has become evident that side effects of radiation are severe in coronary IVR. We encountered two cases of chronic radiodermatitis that resembled morphea clinically. The 1st case was a 72-year-old man. He had undergone ten times of catheter-guided liver artery chemical embolism for his hepatocellular carcinoma. The 2nd case was a 56-year-old man. He had undergone coronary angiography and percutaneous transluminal coronary angioplasty for his acute myocardial infarction. Both cases showed poikilodermic hard plaques on their right backs, and the 2nd case suffered ulceration. Histological examination showed fibrosis without skin appendages in their whole dermis. They were diagnosed as having chronic radiodermatitis on the basis of the clinical and histological observations.

    We report the clinical and histopathological features of expanding hematoma in the skin which developed a few days after skin surgery. A 35-year-old man presented with two enlarging black-reddish nodules on the right cheek and in the right mandibular area. He had a history of subcutaneous hematoma after removal of a wire that had been used for the treatment of left radial bone fracture, but had no other history of a bleeding tendency. Laboratory tests, including those for bleeding time and blood coagulation time, were normal. Histologically, the nodule was composed of multilobular hematomas and cavities encapsulated with thick connective tissue with an inflammatory infiltrate and granulation tissue with dilated blood vessels. The hematoma seemed to have enlarged by bleeding from surrounding capillaries into the central nodule.

    Four cases of superficial angiomyxoma, three men and a woman, were described. Histologically, these tumors showed a multinodular growth pattern and dermal myxoid lesions composed of extended vessels and spindle-shaped stromal cells. There were no epithelial components. The myxoid area was positive for alcian blue staining. The staining was blocked by pretreatment with hyaluronidase, indicating hyaluronic acid deposition. Immunohistochemically, the tumor cells were negative for S-100 protein, positive for vimentin, and focally positive for desmin in one case.
