Adenoid Cystic Carcinoma of the Minor Salivary Glands Metastatic to the Hand

Distant Soft Tissue Metastases: A Series of 30 New Patients and 91 Cases From the Literature

“…3,4,49 The thigh muscles, iliopsoas, and paraspinous muscles are the most frequent sites of reported clinical involvement. 6,8,13,15,24,34,45,46,49,51,54 In the current series, the thigh and arm muscles were equally involved, followed by the chest wall and paraspinous musculature. Soft tissue metastases have been reported in many additional muscles and subcutaneous sites across the body.…”

Thenar muscle metastasis as recurrence of pulmonary squamous cell carcinoma

“…[4][5][6][7] However, the metastasis to the foot and hand is extremely rare (0.007-0.3%), and metastatic hand lesions represent 0.1% of all osseous metastases, while metastases to muscles represent 0.8-16% incidence in autopsy series. 8,9 To our knowledge, the present case is the first report of thenar muscle metastasis resulting from lung cancer. Matsuno et al also presented a case of thenar metastasis from lung cancer, but it was an unusual occurrence of skin metastasis to the thenar eminence, with a histological type of adenocarcinoma.…”

Acinic Cell Carcinoma of the Salivary Gland with Metastatic Spread to the Pancreas

“…Other reported metastatic sites include the cerebrum, thyroid, and spleen [7, 8]. A report from 1979 describes a case of adenoid cystic carcinoma metastasizing to the skin [9]. Overall, metastases to the pancreas are uncommon in solid tumors, with autopsy studies showing pancreatic involvement in widely metastatic disease in 3–12% of all patients with diffuse metastatic disease [10].…”
