- A case-control study of HLA alleles in Brazilian patients with Melkersson-Rosenthal syndrome(2020) GAVIOLI, Camila F. B.; NICO, Marcello M. S.; PANAJOTOPOULOS, Nicolas; RODRIGUES, Helcio; ROSALES, Claudia B.; VALENTE, Neusa Y. S.; FLOREZI, Giovanna P.; V, Silvia LourencoMelkersson-Rosenthal syndrome (MRS) is a neuromucocutaneous disease that manifests by the triad of recurrent orofacial edema (frequently as cheilitis granulomatosa), relapsing facial paralysis and plicated tongue. The cause of MRS remains unknown, but genetic predisposal and a relationship with inflammatory bowel disease are suspected. The objective of this research was to compare the frequency of class I and II HLA alleles in patients with a confirmed diagnosis of MRS with those of a healthy control group. We conduct a case-control study and typed of HLA A, B, C, DR, and DQ using molecular techniques. The study included 36 patients with MRS and 297 patients in the control group. There was an increase in the expression of HLA A*02 (p = 0.0269; OR: 1,79 [1,045-2,973]), HLA DRB1*11 (p < 0,0001; OR: 4,009 [2,214-7,277]), HLA DRB1*13 (not statistically significant) and HLA DQB1*03 (p = 0,0177; OR: 1,829 [1,122-2,978]) and low levels of HLA A*01 (p = 0.0046; OR: 0,097 [0,009-0,538]), HLA DRB1*04 (p = 0.0274; OR: 0,228 [0,053-0,844]), HLA DRB1*07 (p = 0,0091; OR: 0,183 [0,043-0,670]) and HLA DQB1*02 (p = 0.0051; OR: 0,312 [0,143-0,721]) in MRS patients compared with the control group. Crohn disease (CD) patients had disparate genetic profiles versus those with MRS. This single-institution study had a small cohort, because this disease is rare. Conclusions: There is a genetic predisposition toward MRS, involving associated and protective genes.
article 1 Citação(ões) na Scopus Actinic Granuloma Annulare With Scarring and Open Comedones(2017) GAVIOLI, C. F. B.; VALENTE, N. Y. S.; SANGUEZA, M.; NICO, M. M.Actinic granuloma and annular elastolytic giant cell granuloma are variants of granuloma annulare affecting, respectively, sun-exposed and sun-covered skin sites on where, besides classical findings, abundant elastophagocytosis is observed. Here, we report a case of exuberant actinic granuloma annulare that, in addition to extensive scarring, showed multiple overlying open comedones. Markedly dilated follicular infundibula filled with compact masses of laminated keratinous material were observed in proximity to dermal inflammation composed of many histiocytes and multinucleated giant cells in close association with degenerated elastic fibers and abundant elastophagocytosis.- Image Gallery: Unusual images of monilethrix: the eyebrows and the biopsy(2017) ANZAI, A.; MUNCK, A.; FECHINE, C.

- Clinical and Histopathological Findings of Frontal Fibrosing Alopecia-Associated Lichen Planus Pigmentosus(2017) ROMITI, Ricardo; GAVIOLI, Camila Fatima Biancardi; ANZAI, Alessandra; MUNCK, Andreia; FECHINE, Carolina Oliveira Costa; VALENTE, Neusa Y. S.Background: Frontal fibrosing alopecia (FFA) is a primary lymphocytic scarring alopecia occurring mainly in postmenopausal women. A range of facial lesions have been described in FFA, such as lichen planus (LP) pigmentosus, red dots, facial papules, and perifollicular and diffuse erythema. These lesions can be the first sign of FFA. LP pigmentosus is a rare variant of LP. The first description of LP pigmentosus associated with FFA (in 2012) reported 22 cases of LP pigmentosus among 44 cases of FFA affecting South African patients. Methods: We reviewed 16 FFA patients with LP pigmentosus and the histopathological findings of the biopsy of LP pigmentosus in 9 patients. Results: Most patients had intermediate skin phototypes (III-IV; n = 10; 62%). The age at onset of LP pigmentosus ranged from 30 to 60 years. The most common histopathological findings were epidermal atrophy, basal cell degeneration, interfollicular inflammatory infiltrate and melanophages, and perifollicular changes. Other findings not previously described in LP pigmentosus were inflammation and interface changes on sweat duct epithelia (acrosyringium and superior dermal duct), and lichenoid perisebaceitis. Conclusions: Histology of our cases confirmed previous findings and showed a high incidence of perifollicular involvement with occasional changes affecting sebaceous and sweat glands. (C) 2017 S.
