Langerhans Cells (LCs) play a pivotal role in HIV and HPV infection. The migration of LC precursors to skin coincides with the embryonic period of hypospadias development and genetic alterations leading to the formation of hypospadias impact the development of ectodermally derived tissues. We hypothesized that this might be associated with a difference in frequency or morphology of epidermal and dermal LCs in hypospadias patients.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>A total of 43 patients from two centers were prospectively included into this study after parental consent and ethics approval. Epidermal and dermal sheets were prepared from skin samples of 26 patients with hypospadias, 13 patients without penile malformations and 4 patients with penile malformations other than hypospadias. Immunofluorescence staining of sheets was performed with anti-HLA-DR-FITC and anti-CD207\/Langerin-A594 antibodies. Skin sections from 11 patients without penile malformation and 11 patients with hypospadias were stained for Langerin. Frequencies as well as morphology and distribution of epidermal and dermal LCs on sheets and sections were microscopically evaluated. Cell counts were compared by unpaired t-tests.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>There was no difference in frequency of epidermal LCs, Neither on sheets (873\u2009\u00b1\u200961 vs. 940\u2009\u00b1\u200984LCs\/mm<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009=\u20090.522) nor on sections (32\u2009\u00b1\u20093 vs. 30\u2009\u00b1\u20092LCs\/mm<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009=\u20090.697). Likewise, the frequency of dermal LCs (5,9\u00a0\u00b1\u20090,9 vs. 7.5\u2009\u00b1\u20091.3LCs\/mm<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009=\u20090.329) was comparable between patients with hypospadias and without penile malformation. No differences became apparent in subgroup analyses, comparing distal to proximal hypospadias (<jats:italic>p<\/jats:italic>\u2009=\u20090.949), younger and older boys (<jats:italic>p<\/jats:italic>\u2009=\u20090.818) or considering topical dihydrotestosterone treatment prior to surgery (<jats:italic>p<\/jats:italic>\u2009=\u20090.08). The morphology of the LCs was not different comparing hypospadias patients with boys without penile malformations.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>LCs are present in similar frequencies and with a comparable morphology and distribution in patients with hypospadias as compared to children without penile malformations. This suggests that patients with hypospadias are not different from patients with normal penile development considering this particular compartment of their skin immunity.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s12894-019-0551-8","type":"journal-article","created":{"date-parts":[[2019,11,12]],"date-time":"2019-11-12T17:04:27Z","timestamp":1573578267000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Langerhans cells in hypospadias: an analysis of Langerin (CD207) and HLA-DR on epidermal sheets and full thickness skin sections"],"prefix":"10.1186","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1691-7510","authenticated-orcid":false,"given":"Bernhard","family":"Haid","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Reider","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"N\u00e4gele","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne-Fran\u00e7oise","family":"Spinoit","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"Pechriggl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolaus","family":"Romani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helga","family":"Fritsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Oswald","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,11,12]]},"reference":[{"key":"551_CR1","doi-asserted-by":"publisher","first-page":"239","DOI":"10.1159\/000441988","volume":"9","author":"A Bouty","year":"2015","unstructured":"Bouty A, Ayers KL, Pask A, Heloury Y, Sinclair AH.
