Cutaneous vascular tumors: an updated review

Area of Science:

• Dermatopathology
• Oncology
• Vascular Biology

Background:

• Cutaneous vascular tumors present diagnostic challenges for pathologists and dermatopathologists due to overlapping morphologic and immunohistochemical features.
• Advances in understanding vascular neoplasms have led to refined classifications by the International Society for the Study of Vascular Anomalies (ISSVA).

Purpose of the Study:

• To summarize updated clinical, histopathological, and immunohistochemical characteristics of cutaneous vascular tumors.
• To highlight the genetic mutations associated with these neoplasms.
• To provide a comprehensive overview for improved diagnosis and management.

Main Methods:

• Review of current literature on cutaneous vascular tumors.
• Synthesis of information regarding classification, clinical presentation, histopathology, immunohistochemistry, and genetics.
• Focus on entities including infantile hemangioma, Kaposi sarcoma, and angiosarcoma.

Main Results:

• Detailed descriptions of various cutaneous vascular tumors are provided.
• Updated ISSVA classification criteria are discussed.
• Key diagnostic features and genetic associations are highlighted for each entity.

Conclusions:

• Accurate diagnosis and clinical management of cutaneous vascular tumors are improved by understanding their updated characteristics.
• This review serves as a valuable resource for pathologists and dermatologists dealing with these complex entities.
• Continued research into genetic mutations will further refine diagnosis and treatment strategies.
