Breast carcinoma bone metastasis first presenting to single middle phalanx

Acrometastases to the Hand: A Systematic Review

Background and Objectives: The term acrometastases (AM) refers to secondary lesions sited distally to the elbow and knee, representing 0.1% of all bony metastases. By frequency, pulmonary cancer and gastrointestinal and genitourinary tract neoplasms are the most responsible for the reported AM. Improvements in oncologic patient care favor an increase in the incidence of such rare cases. We performed a systematic review of acrometastases to the hand to provide further insight into the management of these fragile patients. We also present a peculiar case of simultaneous acrometastasis to the ring finger and pathological vertebral fracture. Material and Methods: A literature search according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement was conducted using the PubMed, Google Scholar, and Scopus databases in December 2020 on metastasis to the hand and wrist, from 1986 to 2020. MeSH terms included acrometastasis, carpal metastasis, hand metastasis, finger metastasis, phalangeal metastasis, and wrist metastasis. Results: In total, 215 studies reporting the follow-up of 247 patients were analyzed, with a median age of 62 years (range 10–91 years). Overall, 162 out of 247 patients were males (65.6%) and 85 were females (34.4%). The median reported follow-up was 5 months (range 0.5–39). The median time from primary tumor diagnosis to acrometastasis was 24 months (range 0.7–156). Acrometastases were located at the finger/phalanx (68.4%), carpal (14.2%), metacarpal (14.2%), or other sites (3.2%). The primary tumors were pulmonary in 91 patients (36.8%). The average interval from primary tumor diagnosis to acrometastasis varied according to the primary tumor type from 2 months (in patients with mesenchymal tumors) to 64.0 months (in patients with breast cancer). Conclusions: Acrometastases usually develop in the late stage of oncologic disease and are associated with short life expectancy. Their occurrence can no longer be considered rare; physicians should thus be updated on their surgical management and their impact on prognosis and survival.

Metastases to the hand and wrist: an analysis of 221 cases

PURPOSE

To identify demographic trends, survival rates, the most common metastatic locations, and the most common primary malignant tumors in the reports of hand and wrist metastases published over the past 27 years.

METHODS

A keyword search was performed across PubMed, Google, Science Direct, and Springer databases with a time-range restriction set between April 1986 and April 2013. A total of 193 articles were located describing 221 patients. The data were analyzed for patient age, sex, known history of malignancy, primary tumor site, histological diagnosis, metastatic location, hand involvement, and survival rates.

RESULTS

Lung, gastrointestinal tract, and kidney malignancies were the 3 leading metastatic tumors. The mean age among patients was 61 ± 13 years, and involvement among men was almost twice as common as among women. The mean survival from the time of the diagnosis was 7 ± 7 months. There were no predilections for either the right or the left hand. The distal phalanx was the most frequently involved bone, and the thumb was the most frequently involved digit.

CONCLUSIONS

The frequency of published hand and wrist metastasis has increased dramatically within the last decade. Metastases have been reported for every bone of the hand and wrist as well as for the soft tissues. Compared with the previous studies, the mean age of reported patients has slightly increased even though the mean survival time has not changed.

Palmar metastasis of an adenocarcinoma of the esophago-gastric-junction: First case report

INTRODUCTION

Hand metastasis represents only approximately 0.007-0.2% of all metastatic lesions. The most common origin of hand metastasis is the lung, which is approximately 50% of all cases, followed by breast and kidney. Hand metastasis from gastric or esophagic cancer is even much more rare.

PRESENTATION OF CASE

This is the first case report of a metastasis to the palm of hand (tendon) due to an adenocarcinoma of esophago-gastric-junction.

DISCUSSION

While most of the esophagic and gastric carcinomas metastasizes to liver, lungs and brain, the rare possibility of encountering metastasis to the hand either to the bone, but also to the tendon exists. Therefore, we recommend obtaining a thorough history and a detailed clinical examination, plain radiographs, followed by axial imaging techniques like MRI and a histopathologic evaluation.

CONCLUSION

Even if metastatic lesions to the hand are really rare, the surgeon should always be suspicious of a metastatic lesion, when presented with a patient older than 40 years who has a history of cancer.

Metastatic phalangeal osteolysis as an initial presentation of carcinoma colon

Metastatic malignancies of the hand are rare and usually develop from lung, breast, or kidney tumors. Metastases from tumors and sarcomas of the gastrointestinal system are even more uncommon. The authors report a case of differentiated adenocarcinoma of the colon in a 76-year-old man who presented with distal phalangeal metastasis and osteolysis in the form of a painful swelling at the tip of the right little finger of 6 months duration. Computed tomography of the abdomen and colonoscopy revealed a mass in the transverse colon. Diagnosis was confirmed by biopsy. Treatment was given with palliative local radiation and systemic chemotherapy. After 4 weeks of chemotherapy, the patient discontinued treatment and eventually succumbed to the disease.

Two cases of acrometastasis to the hands and review of the literature

This paper reports two cases of acrometastasis to the hands. The first case involved a 78-year-old woman with a permeative osteolytic lesion in her proximal second metacarpal. A biopsy of this lesion suggested a diagnosis of non-small-cell lung carcinoma with secondary osseous metastasis. This was the first presentation of the woman’s primary diagnosis. A single 8-Gy fraction of palliative radiotherapy was delivered to the patient’s left hand. The treatment proved successful: the woman soon experienced pain relief and regained the use of her hand. The second case involved a 69-year-old woman with extensive lytic destruction involving the proximal two thirds of her third metacarpal. This patient had been diagnosed with carcinoma of the breast in 1990. She also received a single 8-Gy fraction of radiation, which improved both her pain and her hand mobility.

An extensive review of the literature uncovered 257 previously reported cases of acrometastasis. Articles were analyzed based on age and sex of the patient, site of the primary carcinoma, metastatic locations within the hand and affected appendage or appendages, the treatment given, and the patient’s length of survival. Men were almost twice as likely to experience acrometastasis as women, and the median age of the patients overall was 58 years (range: 18 months–91 years). Lung, kidney, and breast carcinoma were the three most prevalent primary diagnoses reported in the literature. Cancers of the colon, stomach, liver, prostate, and rectum affected the remainder of the population.

Overall, the right hand was more often host to the metastatic lesions. In addition, almost 10% of the patients experienced lesions in both hands. The third finger was the digit most affected by osseous metastases reported in the literature. Lesions of the thumb, fourth finger, second finger, and fifth finger were less commonly reported. The region of the digit most often affected within the patient population was the distal phalanx. The metacarpal bones, proximal phalanges, and middle phalanges comprised the remainder of the four most frequent acrometastatic sites. In the literature, single lesions were more prevalent than multiple bony lesions.

Based on the reported cases, amputation appeared to be the preferred method of treatment. Radiation, excision, and systemic therapy were the next most frequently used treatments. Patient survival was not well documented within the literature. However, the median survival of patients in the reported cases was 6 months. Thus, our review suggested that a diagnosis of hand metastasis is an indication of poor prognosis.

This report serves to emphasize the importance of properly diagnosing acrometastases. Identifying and effectively treating these metastases in a timely manner can lead to a dramatic improvement in a patient’s quality of life.
