Syringocystadenoma Papilliferum Associated with Poroma Folliculare

A 70‐year‐old woman had a dome‐shaped with a keratinous mass nodule which measured 1.0 × 1.0 × 0.9 cm on the inner canthus. Multiple confluenced vesicles were seen in a small area of the tumor. Histological examination revealed that the tumor had two different portions. The larger portion was poroma folliculare and the smaller was syringocystadenoma papilliferum. We collected cases of syringocystadenoma papilliferum reported in Japan, but there were no other cases associated with poroma folliculare. We suggest that a teratogenic follicle developed poroma folliculare on one side and syringocystadenoma papilliferum on the other.

A case of buttock basal cell epithelioma presenting atypical clinical image.

We present a case of a 47-years-old woman who first noticed a miliary-sized skin tumor on the right buttock about 3 years ago. Two years ago the size increased gradually and it became tender. The patient was admitted to our hospital because a biopsy suggested a basal cell epithelioma (BCE) . At the first visit in our clinic a pale red-violet protruding tumor of 23×20mm size, which showed partial ulceration on its surface, was observed on the right buttock 2 cm from the anus. Under palpitation a slight movability of the 35×47mm subcutaneous mass was observed but on the anal mucous membrane there were no abnormalities. Preoperative CT scanning and sonography showed an extensively spreading tumor that invaded also the subcutaneous fatty tissue, but there were no signs of an infiltration into the sphincter ani. Histological examination after total resection revealed that basal cell-like tumor nests were partially attached to the epidermis an proliferating into the subcutaneous fatty tissue. In this tumor aspect of a solid type as well as aspect of adenoid and keratotic types of BCE were observed. There was no staining of the tumor cells with PAS, Alcian-blue, CEA and S-100 protein. Moreover, there were no significant findings in enzyme histochemical analyses. We reported this BCE case revealed specific clinical feature which developed comparatively rare on the buttock referring some references.

A case of dermatofibrosarcoma protuberans recognizing the transition in the right thigh bone.

61歳, 女性。隆起性皮膚線維肉腫と診断されていた右肩甲部の腫瘤が, 局所再発を繰返すうちに約10年の経過で右大腿骨に転移をきたし, その組織は線維肉腫であった1例を経験したので報告する。転移を生ずるまでの計4回の手術組織標本を再検討してみると, 隆起性皮膚線維肉腫の他に線維肉腫の部分も認められた。隆起性皮膚線維肉腫の一部が線維肉腫の組織を示し, 長期の経過ののち転移を生じた興味深い1例と考えた。

Three cases of Bowen disease in the anal and vulvar regions.

症例1: 61歳, 女。外陰部黒褐色斑。組織学的に大部分が典型的なBowen病であるが一部で真皮内浸潤。症例2: 55歳, 女。外陰部灰黒色斑。組織学的に典型的なBowen病の病巣内に有棘細胞癌様の真皮内浸潤。症例3: 71歳, 女。肛囲黒褐色局面。組織学的に症例1と類似。以上3例の女子外陰部Bowen病の報告を行うとともに, 若干の文献的考察を加え, 女子外陰部Bowen病の治療における早期外科的切除の重要性について述べた。
