The spontaneous regression of tufted angioma. A case of regression after two recurrences and a review of 27 cases reported in the literature.

Background: Tufted angioma, a peculiar angioma that is characterized by tufts of capillary-sized vessels scattered ‘cannonball fashion’ within the dermis, is known, on occasion, to regress spontaneously. However, the appropriate waiting period for spontaneous regression has remained unclear. Objective: To know the appropriate waiting period for spontaneous regression of tufted angioma. Methods: We report here a case of tufted angioma that regressed spontaneously after the lesions had recurred twice. We also review previously reported cases of tufted angioma with spontaneous regression, including cases in the Japanese and non-Japanese literature. Results: In 18 (86%) of the 21 cases, the waiting period was more than 6 months and in 20 cases (95%) it was less than 2 years. Conclusion: The appropriate wait for spontaneous regression might be between 6 months and 2 years.

Delayed Cutaneous Metastasis of Gastric Carcinoma

This paper describes a case of skin cancer resembling carcinoma en cuirasse associated with multiple bone lesions, which were both judged to be due to metastasis of poorly differentiated carcinoma of the stomach, the primary lesion excised ten years previously. Overt bone involvement had been observed for more than two years and a half. Histologic examination of a skin biopsy specimen showed that carcinoma cells had infiltrated into the middle and lower dermis, forming clusters and strands in an abundunce of fibrous stromata. No primary lesion was detected in the remnant stomach at autopsy.

Mongolian spots associated with cleft lip

Of the present series comprising 66 newborns with cleft lip, 13 (20%) had pigmented macules in the labial skin on the lateral side of the cleft. Histological examination using serial sections were performed on 47 cases and showed evidence of dermal melanocytosis in 40 cases (85%) consisting of 33 (70%) without clinically detectable macules and 7 (15%) with obvious pigmented macules. The fusiform cells in the dermis were positive for dopa reaction and anti-melanocyte antibody. The high incidence of dermal melanocytosis is comparable to that of common Mongolian spots in Asian babies.

我々は, Aggressive BCE (Basal Cell Epitheliolna) を (1) 臨床的に再発例, (2) 組織学的に筋層, 軟骨あるいは骨へ達する例のうちいずれかを満たすものと定義づけし, 大分医大皮膚科における59例のBCEをAggressive BCE (14例) とNon-Aggressive BCE (45例) の2群に分け組織学的に比較検討した。その結果, Aggressive BCEではirregular spiky pattern, micronodular nest, peripheral palisading irregularityが組織学的特徴として認められた。炎症細胞浸潤の程度, 潰瘍形成は二つのグループの間に差を認めなかった。これらの結果にもとづき, 当科ではAggressive BCEに対して通常のBCEに対する切除範囲では不十分と考え, SCCに準じた皮膚広範囲切除を行っている。
