Skin metastasis caused by carcinomas is associated with poor prognosis and is a rare and late clinical finding. Skin metastases occur in only 4-6.5% of Stage IV colorectal cancer. We present an unusual case of Stage IV unresectable rectal adenocarcinoma metastasized to the head and face. One and a half years after diagnosis, new skin lesions developed on his face. Biopsy showed mucinous adenocarcinoma consistent with rectal malignancy. Moreover, he died 3 months after the diagnosis of cutaneous metastasis. This case emphasizes the importance of the effect of skin lesions on prognosis in patients with a history of malignancy.

Introduction: Anorectal melanoma (ARM) is rare and highly lethal neoplasm. It has a poorer prognosis compared with cutaneous ones. Sentinel lymph node biopsy (SLNB) has become the preferred method of nodal staging method for cutaneous melanoma.

Digital papillary adenocarcinoma (DPA) is a rare malignant eccrine tumor often misdiagnosed as a benign condition. A 57-year-old Caucasian male with recurrent paronychia and a subcutaneous mass on the distal phalanx of the right fourth digit was diagnosed with DPA after seeking hand surgery evaluation 5 years following onset. A marginal excisional biopsy was positive for infection and DPA, leading to surgical excision with transmiddle phalangeal amputation for negative margins.

Background: Although rare, melanoma confined to the dermis or subcutaneous tissue without evidence of a primary cutaneous site should provoke consideration of melanoma of unknown primary. This diagnosis carries a favorable prognosis when compared with cutaneous metastatic melanoma. Several hypotheses have been proposed for how melanoma of unknown primary develops, two of which were considered in our patient case: (1) spontaneous regression of the primary tumor following metastasis or (2) the traumatic implantation of ectopic melanocytic cells in other tissues, such as the subcutaneous tissue.

Sentinel lymph node biopsy (SLNB) is an important prognostic tool that accurately assesses regional lymph node involvement and guides therapeutic decisions. Material and this prospective study involved 104 patients diagnosed with cutaneous melanoma who underwent SLNB using a radioactive tracer.

Cutaneous metastases of hepatocellular carcinoma (HCC) are uncommon but important to recognize for timely diagnosis and management. We present a case of a 70-year-old man with a history of HCC who developed a painless nodule on the scalp. Histopathological examination and immunohistochemistry confirmed the nodule as cutaneous metastasis of HCC.
