A case of dermal duct tumor (DDT) observed in a 45-year-old male is reported. The lesion was nonspecific clinically. Histological examination revealed dermal tumor masses composed of small, monomorphous basaloid cells arranged around the sweat ducts. There were no atypias and mitotic figures. It is suggested that DDT should be regarded as a distinct eccrine gland tumor that must be differentiated from basal cell carcinoma, hidradenoma, syringoma and above all eccrine poroma.

Porokeratotic eccrine ostial and dermal duct nevus.

A 6-year-old girl with congenital porokeratotic eccrine ostial and dermal duct nevus involving the palmoplantar surfaces (ie, the back of the hands and feet), the limbs, the neck, and the axillae is described. The clinical and histopathologic findings are presented. This entity should be taken into consideration in the differential diagnosis of linear keratotic cutaneous eruptions.

Molluscum contagiosum occurring in an epidermoid cyst.

The histological picture of molluscum contagiosum (MC) is well known: the epidermis grows down into the dermis as multiple, closely packed pear-shaped lobules. The epithelial cells of the outermost layers and the horny layer display typical molluscum bodies. In this paper, we describe an unusual case of MC in a cystic lesion. This lesion was probably due to localisation of the MC virus in the ostium of the pilar infundibulum, followed by obstruction and formation of an inclusion cyst.

Hair-follicle nevus.

A case of a 5-year-old child with a rare nevus of a hair follicle is reported. Histologically it was characterized by many hair follicles within the dermis at the same level of maturation. This nevus must be differentiated from other hamartomas of hair follicles and from Becker's nevus.

[Eccrine-nevus (author's transl)].

The eccrine nevus is an exceptional entity, formed by well-differentiated adnexa which can be classified as hamartoma or organoid nevus. It is characterized by a high degree of structural maturation. The authors report a case of eccrine nevus observed in a 32-year-old woman and compare clinical and histological features of the lesion with literature data.
