Introduction: Pigmented epithelioid angiomyolipoma is a variant of epithelioid angiomyolipoma (EAML) that has not previously been described in children with tuberous sclerosis.

Case Presentation: A 15-year-old boy with tuberous sclerosis had a rapidly enlarging renal mass associated with a left lung nodule. Microscopically it was a pigmented EAML, confirmed by immunohistochemistry.

Discussion/conclusion: The pigmented variant of EAML can arise and metastasize from the kidney of a teenager with tuberous sclerosis.

Aims: The hepatic perivascular epithelioid cell tumour (PEComa), including angiomyolipoma, exhibits diverse morphology and clinical behaviour; however, its prognostic features remain undefined. This study aimed to investigate its histological features and prognostic factors.

Methods And Results: In total, 132 patients were included.

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms, commonly found in the uterus and retroperitoneum. Renal PEComas are exceedingly rare, often posing diagnostic challenges due to their resemblance to renal cell carcinoma (RCC) on imaging. We present the case of an 18-year-old male who presented with non-specific symptoms of fever, chills, and shivering.

BACKGROUND Perivascular epitheloid cell neoplasm (PEComa) is a rare mesenchymal tumor that is evaluated in the same tumor family as angiomyolipoma, sugar cell tumor of the lung, and lymphangioleiomyomatosis. Immunohistochemically, the disease can express melanocytic and myogenic markers, such as HMB45, HMSA1, MelanA/Mart1, and actin. The disease can be seen in almost every organ, especially the uterus and retroperitoneum.

Perivascular epithelioid cell neoplasms (PEComas) and epithelioid angiomyolipomas (EAMLs) are two different denominations for the same "mesenchymal tumor composed of histologically and immunohistochemically distinctive perivascular epithelioid cells". Hepatic PEComa/EAML is a very rare neoplasm, and only 29 case reports of hepatic PEComa and 25 of hepatic EAML have been reported in the current literature. A clear female predominance with a mean age at diagnosis of 42.

Article Synopsis
  • Mesenchymal neoplasms in the nasal cavity, such as angioleiomyoma (AL) and angiomyolipoma (AML), are rare tumors that involve vascular, smooth muscle, and adipocytic components, with unclear classifications as hamartomas or true neoplasms due to limited genetic research.
  • A multi-institutional retrospective study collected data on 15 nasal cavity lesions, primarily affecting older males with obstructive symptoms, and analyzed tissue samples for genetic features.
  • The study discovered that most cases had a high proportion of smooth muscle, with some showing additional components like blood vessels and fatty tissue, while all lesions were positive for smooth muscle markers, indicating their muscular origin.
