“…While cutaneous manifestations tend to resolve with the treatment of the underlying malignancy, some reports suggest nail changes can persist and take longer to resolve [ 65 , 66 ]. Furthermore, lesions tend to reappear as a result of neoplastic recurrence [ 39 , 62 , 67 , 68 ]. Therefore, it is important to observe the full clinical picture as reappearance of the lesions may signify tumor recurrence or development of metastatic disease.…”

Acrokeratosis paraneoplastica, also known as Bazex syndrome, is a relatively understudied yet clinically important dermatological condition that is inextricably associated with squamous cell carcinoma, predominantly of the upper respiratory and gastrointestinal tracts. Manifesting as unique psoriasis-like cutaneous lesions, Bazex syndrome functions as an early warning signal for underlying malignancies, underscoring the urgent need for its timely diagnosis and intervention. Notwithstanding its clinical relevance, the molecular and cellular mechanisms underpinning its pathogenesis are not fully understood. To address these gaps, this comprehensive literature review undertook a meticulous search across reputable databases such as EMBASE, MEDLINE/PubMed, and Web of Science. Our analysis ventures into multiple putative pathogenic pathways, including shifts in Th2 immune responses, aberrant secretion of growth factors, and immunological reactions to tumor-specific antigens. We also detail the clinical phenotypes of Bazex syndrome and their chronological linkage with the corresponding malignancies. Finally, the review evaluates the therapeutic effectiveness of various approaches, including but not limited to targeted cancer treatments, PUVA therapy, and topical corticosteroids. This synthesis aims to arm healthcare providers with a nuanced understanding of Bazex syndrome, facilitating more accurate diagnosis and tailored treatment paradigms.
