An Unusual Cause of Digit Pain: Acrometastasis From Lung Adenocarcinoma.

Acrometastasis accounts for 0.1% of all cases of metastatic cancer, with the most common primary tumor being lung cancer. Since acrometastasis is extremely rare and it generally has a nonspecific clinical presentation, it provides a diagnostic dilemma. We present a case of a 70-year-old female with a painful swollen right index finger which was found to be a metastatic lesion from adenocarcinoma of the lung. The patient expired within one month of diagnosis due to complications from her rapidly progressive metastatic cancer.

A Once-Thought Lipoma Turned Malignant Chondroid Syringoma.

Chondroid syringoma is a relatively rare benign skin appendageal tumor with an incidence of <0.098%. Malignant chondroid syringoma (MCS) arises from cutaneous sweat glands and occurs on the extremities or trunk more commonly in women with only 51 reported cases. Due to the rarity of the disease and lack of published cases of MCS, the diagnostic criteria and treatment protocols are not clear. Based on available recommendations and histological criteria, MCS was diagnosed in a previously classified elbow lipoma following increased size and pain, and skin color changes in a 65-year-old woman.
