Abstract

Purpose: Approximately 10% of all lymphomatoid papulosis (LyP) cases affect pediatric patients. Pediatric LyP is clinically similar to adult LyP, frequently with cutaneous involvement, whereas the affectation of mucosal surface is rare. The LyP clinicopathological spectrum includes type A, B, C, D, E, and LyP with DUSP22/IRF4 rearrangement, with LyP type D representing < 5% of all LyP cases.

Methods: We have previously reported 2 cases of exclusively intraoral LyP type C and E. To date, about 50 cases of LyP type D have been reported; of them, 8 cases, all but one with exclusive skin involvement, corresponded to pediatric patients. Rare LyP type C cases can lack CD30 expression, creating diagnostic difficulties with lymphoma.

Results: Here, we report an extremely rare case of intraoral LyP type D with scarce/absent CD30 expression affecting a 12-year-old white Brazilian boy.

Conclusions: To our best knowledge, this is the first pediatric case of LyP type D with exclusive intraoral involvement.

期刊介绍： Head & Neck Pathology presents scholarly papers, reviews and symposia that cover the spectrum of human surgical pathology within the anatomic zones of the oral cavity, sinonasal tract, larynx, hypopharynx, salivary gland, ear and temporal bone, and neck. The journal publishes rapid developments in new diagnostic criteria, intraoperative consultation, immunohistochemical studies, molecular techniques, genetic analyses, diagnostic aids, experimental pathology, cytology, radiographic imaging, and application of uniform terminology to allow practitioners to continue to maintain and expand their knowledge in the subspecialty of head and neck pathology. Coverage of practical application to daily clinical practice is supported with proceedings and symposia from international societies and academies devoted to this field. Single-blind peer review The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
