Epithelial components derived from folliculo-sebaceous-apocrine germ are evident in apocrine but not in eccrine CS.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Objectives<\/jats:italic>\n                    .\u2014To further characterize pilosebaceous differentiation and to identify the presence of Merkel cells in the areas of follicular differentiation.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Design<\/jats:italic>\n                    .\u2014Histologic type, folliculo-sebaceous differentiation, character of stroma, and presence or absence of Merkel cells by cytokeratin (CK) 20 immunoreactivity were evaluated in 25 CSs (22 apocrine and 3 eccrine) from the surgical pathology files of Henry Ford Hospital (Detroit, Mich).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Results<\/jats:italic>\n                    .\u2014Most CSs occurred in the head and neck region of patients aged 40 years or older. We found no significant difference in sex, age, or location between apocrine and eccrine types. The stroma varied from myxoid (100%) to chondroid (59%), with various amounts of fat (59%) and ossification identified in 2 cases (9%) of apocrine type, but was homogeneously myxoid in the eccrine type. Follicular and sebaceous differentiation was found in 64% and 32% of apocrine CSs, respectively. Only 2 (14%) apocrine CSs with follicular differentiation were positive for CK20 (a few scattered cells in one case and numerous grouped cells in the other in association with follicular epithelium). No correlation was found between type of stroma and the presence of Merkel cells. Scattered Merkel cells were identified in 83% of normal hair follicles and in 33.3% of normal epidermis.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusion<\/jats:italic>\n                    .\u2014A high proportion of apocrine CSs show folliculo-sebaceous differentiation. The presence of Merkel cells in foci of follicular differentiation of CS supports the hypothesis that Merkel cells may be an integral constituent of follicles. To our knowledge, the presence of Merkel cells in CS, particularly in proliferative form, has not been described previously in the literature.\n                  <\/jats:p>","DOI":"10.5858\/2004-128-986-cs","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T17:52:34Z","timestamp":1612979554000},"page":"986-990","source":"Crossref","is-referenced-by-count":24,"title":["Chondroid Syringoma"],"prefix":"10.5858","volume":"128","author":[{"given":"Mohamed E.","family":"Salama","sequence":"first","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Azam","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chan K.","family":"Ma","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Ormsby","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard J.","family":"Zarbo","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahul B.","family":"Amin","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min W.","family":"Lee","sequence":"additional","affiliation":[{"name":"From the Departments of Pathology, Henry Ford Hospital, Detroit, Mich (Drs Salama, Ma, Ormsby, Zarbo, and Lee), North Ottawa Community Hospital, Grand Haven, Mich (Dr Azam), and Emory University, Atlanta, Ga (Dr Amin)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3906","reference":[{"key":"i1543-2165-128-9-986-b1","series-title":"J Cutan Pathol","first-page":"382","article-title":"Mixed tumor of the skin: a model of divergent differentiation.","volume":"11","author":"Mills, S.
