Mucocutaneous Manifestations among Patients with Malignancies at a Tertiary Care Center in Maharashtra: A Cross-Sectional Study

Malignant disorders are a leading cause of mortality and morbidity. Cutaneous manifestations may be presenting features of internal malignancies, leading to diagnosis of occult tumors, while others may occur as adverse reactions to therapeutic modalities. To classify cutaneous manifestations among patients with malignant disorders, document their clinical profile, and analyze them with respect to age, gender, type of malignancy, and treatment. One hundred twenty patients with proven malignancy presenting with mucocutaneous lesions were enrolled in the cross-sectional study. On the basis of history, clinical examination, investigations and skin biopsy, the lesions were classified as (1) Primary cutaneous malignancy, (2) Cutaneous metastasis, (3) Paraneoplastic syndromes, (4) Mucocutaneous manifestations not related to malignancies, (5) Adverse effects secondary to treatment modalities. One hundred twenty patients comprised 70 females (58.3%) and 50 males (41.7%). They were categorized as primary cutaneous malignancy (20.2%), hematological malignancies (15%), solid organ malignancy (50.9%), and gastrointestinal malignancies (5%). HIV seropositivity was seen in two patients (1.6%). Maximum belonged to Category 5 (60, 50%), of which 52 (86.7%) were adverse effects of chemotherapy with single patient showing radiation dermatitis and one patient in Category 3 (0.8%). Eleven patients showed cutaneous metastasis (9.1%), predominantly carcinoma breast. Clinically, primary cutaneous malignancies often presented as ulceronodular growths with squamous cell carcinoma being the most common histopathological type (30%). Anagen effluvium was the most common (35%) manifestation overall and in solid organ malignancies followed by melanonychia (16, 13.33%), cutaneous xerosis (9, 7.5%), and mucocutaneous hyperpigmentation (23, 19.16%). Mucocutaneous manifestations need prompt attention to facilitate timely diagnosis and improved outcomes.
