“…In addition, the present study tends to support the theory of the histopathogenesis of SCM that SCM is a nevoid malformation of the pilo-sebaceous duct junction (5,6,10), rather than that it originates from an obstruction of the outflow of sebaceous material due to keratinization of the follicular lining (2)(3)(4). ADDENDUM A systematic study on SCM (15) including ultrastructural observations which support the view of a sebaceous duct and gland origin for SCM was presented in 1975, but has not been published yet.…”

In order to clarify the site(s) from which steatocystoma multiplex (SCM) originates, five cases of SCM and the normal pilosebaceous apparatus were comparatively examined by electron microscopy. The cyst‐wall of SCM, consisting either of flattened or of undulating horny layer, contained a small number of tonofilaments, desmosomes, and tiny spherical keratohyalin granules. There were variable numbers of lamellar granules which were also frequently observed in the intercellular spaces of the horny layer. Three of the SCM cases included sebaceous cells. The contents of the cysts were mostly amorphous and short‐fibrillar, but sometimes keratinized cells and remnants of lamellar granules were observed. These findings were analogous to those of the normal pilosebaceous apparatus from the level of the lower part of the infundibulum to the outer root sheath Via the sebaceous duct, and were specifically more analogous to those of the sebaceous duct.

“…also called multiple follicular cysts (2) and sebocystomatosis (3). has been relatively well examined by light microscopy (2)(3)(4)(5)(6)(7)(8). but whether it originates from the outer root sheath of the anagen hair (9) or from the sebaceous duct and acini (2-4, 7, 8) is controversial.…”

“…The main Eruptive Vellus Hair Cyst and Steatocystoma multiplex Dermatology 1996:192:64 - 6 6 features are sebaceous glands within the cyst wall, although this feature is not absolutely necessary for the histopathological diagnosis, according to the criteria of Brownstein 12 1 ]. As in our case, steatocystomas may contain hairs, mainly of the lanugo type [11,21,22], EVHC are filled with laminated and amorphous keratinous material as well as fragments of vellus hairs. The cyst wall is covered by several layers of mature squa mous cells [5.…”

Steatocystoma multiplex (SM) and eruptive vellus hair cyst (EVHC) are known as clinically similar but histologically distinct entities, first described by Jamieson in 1873 and Esterly et al. in 1977, respectively. Herein we describe a 24-year-old female patient with both lesions on the anterior chest wall. The biopsy showed portions of two cysts close together with features of SM in one part and features of EVHC in the other part. Our case gives further evidence that these two conditions are closely related. To the best of our knowledge this is the first case where such an anatomically close relationship between these two types of cysts has been described.

“…In our review of the existing literature, we found that the classical histological criteria for EVHC and SM, have been overlapping since in 1957 Contreras ct al. [1], described an SM with vellus hair inside. Several years later.…”

Background of study Steatocystoma multiplex (SM) and eruptive vellus hair cyst (EVHC), are both entities with similar clinical features, but with important histological differences. In the last few years, several authors have reported examples of both cysts with mixed histoiogical features, and have proposed the idea that the two conditions are related.Subjects We report here 3 cases, histological features of SM, EVHC. and the other presenting cysts with mixed histological findings.Conclusions The different histological findings in the cases reported support the idea that SM and EVHC are extremes of a spectrum
