Cutaneous manifestations of internal malignancy

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Skin manifestations are common in oncology.
• Tumor-related skin changes can arise from metastases, hormonal/chemical secretions, or associated dermatoses.
• The mechanisms linking some skin conditions to tumors remain poorly understood.

Purpose of the Study:

• To review the diverse ways tumors impact skin health.
• To categorize tumor-associated cutaneous syndromes and lesions.
• To highlight unexplained associations between neoplastic disease and dermatological conditions.

Main Methods:

• Review of existing literature on tumor-associated skin conditions.
• Classification of cutaneous findings based on etiology (metastatic, secretory, inflammatory, proliferative, nevoid).
• Discussion of recognized but mechanistically unclear associations.

Main Results:

• Skin changes include direct metastases, tumor-secreted chemical/hormonal effects, inflammatory dermatoses, proliferative lesions (benign/malignant), and nevoid states.
• Identifiable cutaneous syndromes can be linked to underlying malignancies.
• Several skin conditions are recognized as associated with tumors, yet their pathogenesis is not fully elucidated.

Conclusions:

• Cutaneous changes represent a significant aspect of cancer diagnosis and management.
• Understanding these associations aids in identifying potential malignancies and managing patient care.
• Further research is needed to elucidate the mechanisms behind unexplained tumor-dermatosis associations.
