Trichoblastic infundibular cyst.

We report 4 cases of an infundibular cyst that histopathologically showed small papillary projections of follicular germinative cells emanating from the basal layer of the cyst wall. Some of these projections branched and formed a reticulated pattern. This cystic lesion is histopathologically distinctive. We propose to designate it as a trichoblastic infundibular cyst because its lining resembles that of an infundibular cyst, yet it has cells that resemble those of the follicular germ in its wall.

Collagen-poly glycolic acid hybrid matrix with basic fibroblast growth factor accelerated angiogenesis and granulation tissue formation in diabetic mice.

Because poor skin wound healing associated with diabetes is thought to be partly a result from impaired angiogenesis, treatments that improve angiogenesis could have important clinical applications. We herein report the effects of novel developed material, collagen-poly glycolic acid fiber hybrid matrix, being used together with basic fibroblast growth factor to promote wound healing of full-thickness skin defects on the back of type 2 diabetic Lepr(db) mice. Our data indicates that this therapeutic approach markedly promotes angiogenesis and granulation tissue formation in comparison with other conditions 14 days after wounding.

Mucinous carcinoma of the skin with apocrine-type differentiation: immunohistochemical studies.

We investigated the pathway of differentiation in a case of mucinous carcinoma of the skin (MCS) arising on the right temple of a 70-year-old man. Histopathologic findings of the tumor showed evidence of apocrine-type differentiation such as distinctive decapitation secretion. Additionally, by employing a panel of antibodies, the immunohistochemical staining pattern of tumor cells was shown to be compatible with that of apocrine glands. Although the differentiation of this neoplasm remains controversial, the findings in our case suggest apocrine differentiation.
