Leiomyoma is an uncommon tumor of the kidney. The authors report a rare case of renal leiomyoma in a 39-year-old male patient who presented with a right flank mass. Laparoscopic nephrectomy was performed. The histopathology and immunohistochemistry confirm the diagnosis of renal leiomyoma. The review of literature in the clinicoradiopathological correlation was illustrated.

Summary: Hereditary leiomyomatosis and renal cell cancer (HLRCC) is an autosomal dominant condition characterized by multiple cutaneous and uterine leiomyomas and renal cell cancer (RCC). HLRCC is caused by germline pathogenic/likely pathogenic (P/LP) variants in the fumarate hydratase (FH) gene on chromosome 1q42.3, encoding the mitochondrial enzyme responsible for the conversion of fumarate to malate in the Krebs cycle.

Fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) is a clinically aggressive tumor with high rates of progression and mortality. A wide range of morphological variations has been observed in FH-deficient RCC, initially described as type 2 papillary RCC or unclassified RCC. Here, we report a case of FH-deficient RCC with rare signet ring cells features.

Fumarate hydratase (FH)-deficient renal cell carcinoma (RCC) is a renal neoplasm associated with FH loss, aggressive behaviour, and poor survival. We present a histopathological and immunohistochemical overview of FH-deficient RCC to infer significant features for its differential diagnosis. In this study, FH-deficient RCC tissue samples from patients who underwent surgical resection or biopsy at a single institution between July 1995 and August 2022 were reviewed by conventional haematoxylin and eosin staining, immunohistochemistry, and whole genome analyses.

The management of children with syndromes associated with an increased risk of benign and malignant neoplasms is a complex challenge for healthcare professionals. The 2023 AACR Childhood Cancer Predisposition Workshop provided updated consensus guidelines on cancer surveillance in these syndromes, aiming to improve early detection, intervention, and reduce morbidity associated with such neoplasms. In this paper, we review several of the rare conditions discussed in this workshop.

Background: Although blood urine is frequently observed in dromedary camels, little attention is gained and only it was reported as case reports.
Aim: This study was carried out to examine dromedary camels suffering from red urine syndrome from the points of clinical, etiological, hematobiochemical, ultrasonographic, and pathological characteristics.
Methods: Thirty-one camels with red urine and fifteen controls were enrolled.
