Occult carcinoma of the lung presenting as pain in the hallux: a case report.
Metastatic tumors to the hands and feet (acrometastases) are rare. We report a case in which the primary presentation of a lung carcinoma was a metastatic lesion to the distal phalanx of the hallux. A 60-year-old woman was evaluated for pain in her big toe. Radiographs and computed tomography suggested a benign lesion in the distal phalanx of the hallux, but curettage and biopsy revealed metastatic adenocarcinoma. A chest x-ray revealed a mass in the right perihilar region, which was confirmed by CT, bronchoscopy, and biopsy as carcinoma of the lung. A review of the literature reveals that there is a tendency toward delayed diagnosis in similar cases, especially when the primary lesion is asymptomatic. A high index of suspicion is needed for early diagnosis in such cases.
