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.

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.

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.
