Occult lung malignancy presenting with finger pain: a case report

Abstract

Introduction: Lung cancer is currently one of the most common malignancies in the world. Early detection is an important prognostic factor. Unfortunately, initial symptoms may be vague and a substantial proportion of cases present with the effects of metastases.

Solitary acrometastasis of the phalanx as initial presentation of an oligometastatic Kirsten rat sarcoma viral oncogene homolog-mutated lung adenocarcinoma: a case report

“…Benign diseases are usually first suspected, and the differential diagnosis is made against osteomyelitis, rheumatoid arthritis, gout, or a traumatic lesion [ 7 – 9 , 11 , 18 ]. Before considering a malignant entity diagnosis, an extended workup should be done, including evaluation of patient history (recent traumatic events, context of gout or other immune diseases), physical examination, review of laboratory data (autoimmune panel, acute phase reactants, uric acid values), or diagnostic imaging [ 9 , 11 , 18 ]. In this reported case, the easy access to imaging allowed an earlier suspicion of an oncological diagnosis.…”

Digital acrometastasis as presentation of pulmonary adenocarcinoma

“…pulmonary neoplasms have access to the peripheral arterial system or, when associated with traumatic mechanisms, by increased blood supply to the region and release of chemotactic factors. [8][9][10] The correct diagnosis of the presence of hand acrometastasis is fundamental, since it can be the initial manifestation of occult neoplasia, and the ease with which the symptoms mimic other benign entities (1) . Its radiographic translation is usually that of a lytic lesion with cortical disruption or poorly defined margins, 7 always requiring a complementary analytical evaluation in case of suspicion.…”

“…3 Given this fact, its approach tends to be mainly palliative, focused on the relief of pain and return of normal function. 4,8,9 The authors believe in the importance of publicizing this type of cases, to alert clinicians to their presence, as well as maintaining a high alert level for their presence.…”
