ABSTRACT
Cutaneous metastases are the result of complex interaction between the tumor cells ("seed") and the host environment ("soil"). Metastases to the skin can be an early sign of internal malignancy or represent recurrence of the primary tumor and portends a poorer prognosis. Invasion and metastasis are the hallmarks of on cogenesis. Skin is the largest organ in the body, but the incidence of metastases is low. With advances in molecular biology, factors responsible for the initiation and perpetuation of metastatic tumor cells at distant sites are being elucidated. The concept of "pre-metastatic niche" and interaction between various chemokines has given a new outlook in understanding the organ specificity of metastatic tumor cells. We present two cases of cutaneous metastases with interesting clinical findings correlating with its biologic subtypes.
ABSTRACT
Hand and foot syndrome (HFS) is a well-known complication of chemotherapeutic drugs given in a dose-dense manner. Our patient was a 52-year-old female with metastatic breast carcinoma on salvage chemotherapy regimen with docetaxel at a dose of 60 mg/m(2). The patient had grade 3 HFS characterized by symmetrical, tender, and erythematous skin lesions over the palms and soles associated with dysesthesia necessitating interruption of treatment. She developed this syndrome at a much lower dose than previously described due to her altered hepatic function. An insight regarding this unique distressing side-effect and assessment of various contributing factors would help us identify and treat the patient at the earliest.
