This condition often presents with ambiguous genitalia, atypical pubertal development, or unexpected menstrual activity. This case report details a 14-year-old phenotypic male with ambiguous genitalia, cyclic perineal bleeding, and synchronous bilateral dysgerminoma, underscoring the diagnostic complexities and management challenges encountered in resource-constrained settings. <b>Case Presentation:</b> A 14-year-old individual assigned male at birth and raised as a boy presented with progressive abdominal distension, cyclic perineal bleeding, and absent male secondary sexual characteristics. Physical examination revealed ambiguous genitalia, a small phallic structure, a perineal opening with menstrual blood, and no palpable gonads. Hormonal analysis revealed elevated lactate dehydrogenase and gonadotropins, low testosterone levels, and increased estradiol. Imaging revealed an abdominopelvic mass highly suggestive of ovarian malignancy, and vaginal exploration confirmed Müllerian structures. Laparotomy revealed a 16-cm × 18-cm right adnexal mass, and histopathology confirmed dysgerminoma. The patient was lost to follow-up but returned 6 months later with a contralateral (left) adnexal mass, prompting oncologic referral. <b>Conclusion:</b> Ovotesticular DSD with bilateral dysgerminoma is exceedingly rare and poses significant diagnostic and therapeutic challenges. Early diagnosis, multidisciplinary management, and timely oncologic intervention are crucial for optimizing patient outcomes, especially in resource-limited settings. This case underscores the critical need for heightened awareness, improved access to karyotyping, genetic and hormonal assessments, and long-term follow-up for individuals presenting with ambiguous genitalia and atypical pubertal development.</p>","PeriodicalId":9623,"journal":{"name":"Case Reports in Pediatrics","volume":"2025 ","pages":"7659991"},"PeriodicalIF":0.7,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12178766/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It arises from the uncontrolled proliferation of immature myeloid dendritic cells, leading to their accumulation in various sites. Recent studies indicate that Langerhans cell histiocytosis is a clonal neoplastic disorder driven by mutations in the MAP kinase pathway. When the bones are involved, the condition is often asymptomatic, but it can cause pain or soft tissue swelling, with the skull being the most affected site. <b>Case Presentation:</b> We present the case of a 9-year-old boy who presented with painful left periorbital swelling. He initially underwent empirical medical therapy for suspected periorbital cellulitis. Due to a lack of improvement in symptoms, radiological assessment was subsequently performed, revealing frontoethmoidal-orbital bone resorption and a mass of ambiguous nature with peripheral enhancement in T1-weighted sequences. Following an ENT evaluation, a biopsy was performed using an endoscopic endonasal approach. The histological examination confirmed the presence of Langerhans cell histiocytosis, with unifocal localization in the frontal bone. Consequently, the patient began chemotherapy following the LCH-IV protocol, the international collaborative treatment protocol for children and adolescents with Langerhans cell histiocytosis. <b>Conclusions:</b> Langerhans cell histiocytosis is a rare disease that may present with involvement of the frontal and ocular regions. Although periorbital cellulitis is initially treated with first-line medical therapy, if there is no improvement, radiological assessment and subsequent histological examination become essential for prompt diagnosis and appropriate therapeutic intervention.</p>","PeriodicalId":9623,"journal":{"name":"Case Reports in Pediatrics","volume":"2025 ","pages":"8892923"},"PeriodicalIF":0.7,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12126256/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most patients develop refractory anemia in early infancy, rapidly followed by multiple complications such as failure to thrive, muscle hypotonia, pancreatic insufficiency, and renal tubulopathy. Although the definitive diagnosis is established by mtDNA sequencing, bone marrow (BM) cytology is a cornerstone of diagnosis, typically revealing precursor vacuolization and ring sideroblasts. We report here three cases of patients with PS encountered in our institution and summarize the clinical and hematological features of PS through a systematic review of the literature. The first symptoms mostly appear during the first month of life and rarely after 18 months. Hyporegenerative anemia, a hallmark of the disease, is the most common initial symptom, followed at a distance by neutropenia and thrombocytopenia. Gastrointestinal and metabolic symptoms such as failure to thrive and lactic acidosis are the most frequent non-hematological symptoms, even in the rare cases without hyporegenerative anemia. Vacuolization of BM precursors, observed in the vast majority of PS patient BMAs, is not influenced by the patient's age at sampling. Ring sideroblasts, the other feature of PS BMAs, are less frequent than progenitor vacuolization but increase significantly after 6 months of age. These abnormalities are just as common in patients with or without hematological symptoms, suggesting that BMA should be performed in all suspected PS cases, despite the absence of anemia.
