Vascular leiomyomas, or angioleiomyomas, are benign tumours originating from smooth non-striated muscle. Leiomyomas in the hand are uncommon and their pre-operative diagnosis is difficult. We report a 65 year-old woman who developed a vascular leiomyoma arising from the deep palmar arterial arch.

Fumarate hydratase tumor predisposition syndrome (FHTPS) is caused by germline fumarate hydratase (FH) pathogenic variants (PVs). Most women with FHTPS develop FH-deficient (FHD) uterine leiomyomas (ULs), which arise 10 to 15 years earlier than aggressive FHD-renal cell carcinoma. We evaluate a previously proposed FHTPS screening strategy for women with ULs.

Sinonasal leiomyoma is an exceptionally rare neoplasm arising from smooth muscle cells within the sinonasal tract. This abstract presents a case study of a 43-year-old male patient diagnosed with sinonasal leiomyoma, a distinctive and challenging entity in otolaryngology. The patient presented with a complex clinical history, including a 2-year interval between initial evaluation and definitive diagnosis.

Leiomyoma with bizarre nuclei (LM-BN) is a rare variant of leiomyoma with a benign clinical course. In contrast, leiomyosarcoma (LMS) is a high-grade, malignant neoplasm characterized by high recurrence rates and poor survival. While LM-BN and LMS show distinct morphologies, they share similar immunoprofiles and molecular alterations, with both considered 'genomically unstable'.

Purpose: The aim was to find bony landmarks of the pelvis for the origins and routes of uterine arteries, hoping to improve speed and safety of embolization procedures (leiomyoma, post-partum bleedings…).
Methods: We carried out a study based on the analysis of CT-angiographies in arterial phases of whole-body scans. Two measurements were done per artery, one from the origin of uterine arteries to a first perpendicular line passing through the lowest part of the sacroiliac joint, another one from the beginning of the parametrial segment from a second parallel line passing by the acetabular roof.

Aggressive angiomyxoma (AA) is a very rare tumour arising from the vulvovaginal mesenchymal tissue. The literature has not reported its co-existence with hidradenitis suppurativa (HS). A 30-year-old female presented with a giant pedunculated mass arising from a scarred and disfigured perineum for 3 years.
