- Abstract: Adrenal cortical carcinoma (ACC) is a rare malignancy, and oncocytic ACC (OAC) is a rare histopathologic variant of ACC, with <70 cases documented worldwide as of 2021. This is a case of a 64-year-old female initially presenting with epigastric-to-periumbilical pain, left flank pain, nausea, vomiting, and bloatedness. Computed tomography (CT) urogram revealed a 12.2 x 12.7 x 15 cm left adrenal mass, with pulmonary metastases on chest CT. The patient was clinically and biochemically unremarkable based on the hormonal panel. Left thoracoabdominal adrenalectomy was done, and the left adrenal mass was identified as a high-grade non-functioning OAC on histopathology and immunohistochemistry. The patient showed clinical improvement on chemotherapy with etoposide, cisplatin, doxorubicin (EDP), without mitotane, due to local unavailability. In conclusion, while EDP + mitotane is the standard therapy for metastatic cases, EDP alone showed promising outcomes in improving quality of life and resolving paraneoplastic neuropathy in the absence of mitotane. To date and to the best of our knowledge, this is the first documented case of non-functioning OAC in the Philippines. DS-related Kaposi sarcoma (KS) progresses rapidly with early mucosal and systemic involvement. Early diagnosis and treatment are crucial as they significantly impact the outcome. This is a case of disseminated cutaneous and gastrointestinal KS in a 24-year-old Filipino male living with HIV, presenting with hyperpigmented violaceous subcutaneous nodules, odynophagia, progressive dysphagia, and symptomatic anemia. Capsule endoscopy demonstrated utility in diagnosing gastrointestinal KS lesions, highlighting its crucial role when conventional upper endoscopy was challenging due to oropharyngeal involvement. Diagnostic limitations, mainly the unavailability of human herpesvirus-8 (HHV-8) immunohistochemical stain, were addressed through high clinical suspicion. Multidisciplinary approach including chemotherapy with liposomal doxorubicin, radiotherapy, and supportive care eventually yielded good clinical response. This case emphasizes the importance of early diagnosis, timely intervention, and long-term surveillance in achieving favorable outcomes for patients with KS despite some diagnostic limitations.
