Eruptive pseudoangiomatosis.

Eruptive pseudoangiomatosis (EPA) is a rare, self-limiting exanthem, which is known to occur primarily in children. It is characterized by an eruption of distinctive erythematous angioma-like papules often surrounded by a pale halo, with histological findings distinct from that of true angiomas. We describe three women with angioma-like papules. The biopsy specimens from them showed a unique histological appearance consisting of dilated dermal blood vessels with plump endothelial cell and perivascular lymphocytes. On the basis of the clinical and histological findings, we present the adult cases of eruptive pseudoangiomatosis and their etiology.

Calcinosis cutis of the fingertip associated with Raynaud's phenomenon.

Cutaneous calcification may be divided into four major categories: (i) dystrophic; (ii) metastatic; (iii) idiopathic; and (iv) iatrogenic. Dystrophic calcification is the most common type of calcinosis cutis and is associated with a variety of diseases. It most notably occurs in connective tissue diseases. Diffuse and limited cutaneous systemic sclerosis is an example of connective tissue diseases that frequently show calcinosis. We experienced a case of fingertip calcinosis cutis associated with Raynaud's phenomenon. The patient had no previous trauma, skin lesion or systemic connective tissue disease. We propose that calcinosis cutis of the fingertip may result from chronic ischemic injury caused by Raynaud's phenomenon.

Mucinous eccrine nevus.

A 46-year-old man with an erythematous, tender, swollen patch on the dorsum of his left fourth toe visited us. The biopsied tissue showed a proliferation of normally structured eccrine glands and ducts surrounded with abundant materials confirmed as mucin by toluidine blue stain. Mucinous eccrine nevus is an extremely rare entity, and only two cases have been reported in the literature. We describe a case of mucinous eccrine nevus which was late in onset and presented as a swollen patch.
