An Epithelioid Hemangioma Camouflaged As Radial Aneurysm.

Epithelioid hemangioma (EH) is an uncommon benign vascular lesion usually present as subcutaneous nodules in the head and neck area. Sometimes, these lesions can occur in the peripheral arteries, and when they do, they can be mistaken for aneurysmal dilatations of that respective vessel. We report a case of a 43-year-old male who underwent surgical recession of a radial aneurysm, which after anatomopathological examination, revealed an EH.

Atypically Located Solitary Neurofibroma of the Ulnar Nerve as Inaugural Presentation of a New Genetic Variant of Neurofibromatosis Type 1: A Case Report.

We report the case of a 34-year-old woman with hypothenar pain due to a solitary neurofibroma (NF) of the ulnar nerve, with an extrafascicular location, outside Guyon canal, with no clinical evidence of associated neurologic impairment, who was successfully treated with surgical resection. The identification of this isolated tumor led to the diagnosis of a new genetic variant of neurofibromatosis type 1 after genome sequencing. At the 1-year follow-up, the patient remains asymptomatic without recurrence or other peripheral nerve sheath tumors. A solitary NF of a deep-seated nerve is extremely rare, especially in the context of neurofibromatosis type 1. To our knowledge, there are no reports of a NF of the ulnar nerve with an extraneural location. In the presence of a solitary NF related to a deep-seated peripheral nerve, neurofibromatosis type 1 should always be excluded.

Behçet Syndrome and Crohn's Disease: What Are the Differences?

Behçet syndrome (BS) is a variable vessel vasculitis that has pleiotropic manifestations. A 43-year-old male with a previous diagnosis of Crohn's disease (CD) presented with deep venous thrombosis and bilateral superficial femoral artery aneurysms. A diagnosis of BS was made, and the patient was treated aggressively with immunosuppressive therapy and bilateral bypass surgery, attaining a favourable outcome. CD has many features that overlap with BS, and it may be challenging to distinguish between these two conditions, as our case illustrates. Nonetheless, the combination of venous thrombosis and arterial aneurysms should point the clinician towards a diagnosis of BS. LEARNING POINTS: Behçet syndrome is a variable vessel vasculitis of unknown aetiology that has pleiotropic manifestations.Crohn's disease has many overlapping features with Behçet syndrome, namely gastrointestinal, cutaneous, articular, ocular and cardiac manifestations.The combination of venous thrombosis and arterial aneurysms should point the clinician towards a diagnosis of Behçet syndrome.
