Clinical and Molecular Spectrum of Sporadic Vascular Malformations: A Single-Center Study.

Biomedicines 2022 Jun 20;10(6). Epub 2022 Jun 20.

Dermatology Unit and Genodermatosis Unit, Genetics and Rare Diseases Research Division, Bambino Gesù Children's Hospital, IRCCS, Piazza Sant'Onofrio 4, 00165 Rome, Italy.

Sporadic vascular malformations (VMs) are a large group of disorders of the blood and lymphatic vessels caused by somatic mutations in several genes-mainly regulating the RAS/MAPK/ERK and PI3K/AKT/mTOR pathways. We performed a cross-sectional study of 43 patients affected with sporadic VMs, who had received molecular diagnosis by high-depth targeted next-generation sequencing in our center. Clinical and imaging features were correlated with the sequence variants identified in lesional tissues. Read More

Case Rep Pediatr 2022 24;2022:8245139. Epub 2022 May 24.

Department of Pediatrics, Mohammed VI University Hospital, Oujda, Morocco.

Bean syndrome (BS) or blue rubber bleb nevus syndrome is a rare clinical entity characterized by venous malformations mainly in the skin and digestive tract, whose hemorrhagic complications can be life threatening. We report a case of Bean syndrome in a 3-year-old child of nonconsanguineous parents, in whom the diagnosis of miliary hemangiomatosis was initially made in view of a huge mass on the left thigh, taking the knee, and then the progressive appearance of a skin disorder with bluish swellings of variable sizes spread over the whole body. The patient was put on beta-blockers but without improvement. Read More

Blue Rubber Bleb Nevus Syndrome: A Rare Case of Gastrointestinal Hemorrhage Necessitating Bowel Resection.

Am Surg 2022 Apr 17:31348221084949. Epub 2022 Apr 17.

Department of Pediatric Surgery, 14423Arkansas Children's Hospital, Little Rock, AR, USA.

Blue Rubber Bleb Nevus Syndrome is a congenital rarity that manifests as vascular malformations throughout the body, including the gastrointestinal tract. With fewer than 300 cases reported, the etiology and clinical course is poorly understood; however, the literature suggests mutations on chromosome 9 result in unregulated angiogenesis. We present the case of a young female treated for anemia of unknown etiology who presented in hemorrhagic shock due to gastrointestinal hemorrhage necessitating small bowel resection, with cutaneous, intestinal, hepatic, and lingual vascular malformations associated with a single somatic pathologic mutation.

What to Look Out for in a Newborn with Multiple Papulonodular Skin Lesions at Birth.

Dermatopathology (Basel) 2021 Aug 17;8(3):390-417. Epub 2021 Aug 17.

Department of Dermatology, Necker-Enfants Malades Hospital, APHP, 75015 Paris, France.

Multiple papulonodular skin lesions at birth can indicate the presence of various benign and malignant disorders. Although the lesions' clinical aspect (color and consistency, in particular) may steer the clinician towards one disorder or another (infantile myofibromatosis, xanthogranuloma, or metastatic neuroblastoma), the diagnosis can only be confirmed by the histopathologic assessment of a biopsy. In neonates, a rapid but accurate diagnosis is critical because skin lesions may be the first manifestation of a malignant disorder like leukemia cutis or metastatic neuroblastoma. Read More
