Eruptive vellus hair cyst with singular histologic finding

Persistent Milia, Steatocystoma multiplex and Eruptive Vellus Hair Cysts: Variable Expression of Multiple Pilosebaceous Cysts within an Affected Family

“…The biopsies of the mother’s cysts revealed the typical features of steatocystoma in the biopsy taken from one of the larger cysts located in the trunk and features of EVHC in the biopsy taken from one of the cysts of the face. The association of a sebaceous gland near the cyst, as observed in this case, has previously been described in EVHC [7], but some authors have suggested that cysts with these histopathologic features might be considered ‘hybrid cysts’ with features of both SM and EVHC [8, 9, 10, 11]. …”

A Case of Multiple Pilosebaceous Cysts

“…In the larger cyst in our patient, the size and the construction of the cyst wall were in accordance with SM, but the absence of sebaceous glands or atrophic sebaceous elements adjacent to or within the cyst wall differed from typical SM. The overlapping histopathological features of EVHS and SM have been described [6,7,8]. Therefore, we diagnosed the papules as MPSC.…”

Acquired multiple pilosebaceous cysts on the face having the histopathological features of steatocystoma multiplex and eruptive vellus hair cysts

“…Urbina et al . reported a case of EVHCs in which sebaceous glands were observed within the cyst wall 11 . Sexton and Murdock 12 have described a case of EVHCs in which the cyst wall showed an eosinophilic cuticle in the luminal border, similar to that of SM.…”

“…The cyst wall consists of several layers of mature squamous cells 3,6 similar to those of infundibular or the isthmus portion of hair follicles 3,4,9,10 . Rarely, there are sebaceous glands within or near the cyst wall 11 …”

“…Over recent years, several studies have revealed histopathological similarities, 11–13 and overlapping histopathological features 9,11,12,14 between SM and EVHCs. In addition, patients have been described that had lesions of both SM and EVHCs 8,9,15 .…”
