Infantile hemangiomas (IHs) are common benign vascular tumors that affect infants. In this case report, we detail the natural course of an IH in an infant monitored over four months without medical intervention, illustrating the benign progression and potential for spontaneous stabilization of such lesions. The aim was to observe changes in the size and morphology of the hemangioma, alongside the infant\'s overall health and developmental milestones, through regular clinical assessments. This case presented a challenge as the patient\'s parents lacked English fluency, lacked healthcare access, and had low socioeconomic status. It highlights the importance of individualized patient care, advocating for careful observation and restraint in the application of pharmacological treatments when clinically unnecessary. The report contributes to existing pediatric dermatology knowledge by emphasizing the natural benign behavior of IH and the need for a balanced approach to treatment decisions, ensuring safe and favorable long-term outcomes for patients.

We present the clinical course of an 8-month-old infant with a giant cutaneous hemangioma resulting in high-output heart failure and pulmonary hypertension. The lesion was successfully embolized and excised, with rapid resolution of heart failure and improvement in pulmonary hypertension.

Vertebral hemangiomas (VHs) are benign vascular tumors that develop from the endoderm of blood vessels, although their exact pathogenesis is poorly understood. Most hemangiomas are small, about a third are multiple in number, and a very small number of these hemangiomas cause symptoms. Even more rare are aggressive VHs, which comprise a small number of all VHs, and are associated with expansion and extraosseous extension into the paraspinal and epidural spaces. Management of aggressive VHs involve pre-op embolization, spinal surgery, and reconstruction. Pain management, physical rehabilitation, and close neurological follow-up are imperative to near-total recovery. Aggressive VHs are most commonly seen in the thoracic region but may rarely involve a large number of vertebrae. Cutaneous hemangiomas, when seen along with VHs, are often metameric.  We present a rare and challenging case of compressive myelopathy and a large cutaneous hemangioma or a \"purple shoulder\", found during an exam in a young male. He was found to have an extensive VH extending through 13 vertebral levels (C7 to D12), non-metameric to the cutaneous lesion. A thorough physical examination and evaluation along with prompt surgical treatment were the cornerstone of treatment and prevention of permanent neurological deficits.

BACKGROUND: Blue rubber bleb naevus syndrome (BRBNS) is a rare disease that usually presents with multiple venous malformations in the skin and gastrointestinal tract. Lesions located in the gastrointestinal tract always result in chronic gastrointestinal bleeding and severe anemia. The successful management of BRBNS with sirolimus had been reported in many institutions, due to its impact on signaling pathways of angiogenesis. However, the experience in treatment of neonates with BRBNS was limited.
METHODS: A 38-day-old premature female infant born with multiple skin lesions, presented to our center complaining of severe anemia and hematochezia. Laboratory examination demonstrated that hemoglobin was 5.3 g/dL and contrast-enhanced abdominal computed tomography showed multiple low-density space-occupying lesions in the right lobe of the liver. She was diagnosed as having BRBNS based on typical clinical and examination findings. The patient was treated by transfusions twice and hemostatic drugs but symptoms of anemia were difficult to alleviate. A review of BRBNS case reports found that patients had been successfully treated with sirolimus. Then the patient was treated with sirolimus at an average dose of 0.95 mg/m2/d with a target drug level of 10-15 ng/mL. During 28 mo of treatment, the lesion was reduced, hemoglobin returned to normal, and there were no adverse drug reactions.
CONCLUSIONS: This case highlights the dosing regimen and plasma concentration in neonates, for the current common empiric dose is high.

BACKGROUND: Though the combination/collision of nevi or lentigo simplex and hemangiomas is frequent, the malignant collision tumor melanoma-hemangioma is exceptional and can sometime clinically simulate a benign collision. To date, a series of collision tumors of hemangiomas associated with either benign or malignant melanocytic skin lesions (MSL) has yet to be studied by non-invasive imaging and clinico-pathologic correlates.
METHODS: We present 10 cases of patients with collision tumors of hemangioma with different MSL including: 2 in situ lentigo-maligna melanoma, 1 invasive melanoma, 5 melanocytic nevi, and 2 lentigo simplex. The clinical aspect along with the dermoscopic and reflectance confocal microscopy (RCM) features is described and compared with histopathologic findings.
RESULTS: Dermoscopic examination allows to recognize a dark ring in malignant collision melanoma-hemangioma and a jelly ring sign in benign collision of nevi/lentigo simplex-hemangioma. These peculiar features were confirmed by RCM and histopathologic findings.
CONCLUSIONS: Two simple dermoscopic clues confirmed by RCM features can be proposed to help distinguish between benign and malignant collisions tumors.

Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. However, diffuse hepatic hemangioma can develop even in patients with single cutaneous hemangioma. This highlights the importance of physical examination and screening ultrasound in these patients.

Klippel-Trenaunay-Weber Syndrome (KTWS) is a rare entity. It includes cutaneous hemangioma (Port-wine stains) of the face and extremities with associated varicosities and hypertrophy of underlying soft tissue and bone. Craniofacial involvement is rare in this syndrome. We report a case of Klippel-Trenaunay-Weber Syndrome who presented with craniofacial deformity leading to deviated nasal septum, nasal obstruction and intermittent nasal bleed. These patients can have involvement of oral cavity and nasal mucosa with angiomatous malformation, which can give rise to epistaxis and excessive bleeding during oral and nasal surgeries. We discuss the review and management of such cases from Otolaryngologists point of view.
