“…The mechanism of the metalloptysis is unclear. Presumably, the staples are situated very close to some small bronchus which are large enough to be able to contain the staples, which are then coughed up [2]. This in turn elicits inflammation and infection, thereby promoting erosion of the materials into the larger bronchi [6].…”

“…Surgical staplers are widely used when performing wedge lung resections [1]. Metalloptysis is an uncommonly described phenomenon characterizing the expectoration of surgical clips [2]. During thoracic surgery, it has been described as involving a bovine pericardium staple line in the lung, abnormal lung parenchyma, or pulmonary infection [2].…”

“…Metalloptysis is an uncommonly described phenomenon characterizing the expectoration of surgical clips [2]. During thoracic surgery, it has been described as involving a bovine pericardium staple line in the lung, abnormal lung parenchyma, or pulmonary infection [2]. One interesting case report describes the migration of a piece of the bovine pericardium as causing obstructive pneumonia [3].…”

A 40‐year‐old man had considered himself to be robust, with the exception of an earlier diagnosis of hepatitis C. He underwent a wedge resection of the lung, at the left upper lobe (LUL), mimicking an anterior mediastinal tumor. A pathology report showed a 5 × 5 × 2.5 cm grey‐brown and yellowish lesion in a resected 9 × 6 × 3 cm of the lung, with a subsequent diagnosis of organizing pneumonia. The patient recovered uneventfully and was discharged while in a stable condition. One month later, he was admitted and given empiric antibiotic treatment for a lung abscess due to a compound symptom for three weeks after discharge. Although his symptom improved readily, a computed tomography (CT) of the chest disclosed a steady consolidation over the LUL. The fluctuation with haemoptysis and a productive cough spanned 11 months, until a bout of aggravated symptoms including foul and blood‐tinged sputum which mingled with an intermittent high fever became evident. The patient then underwent a bronchoscopy, which surprisingly revealed a metal material impacted over the orifice of the LUL bronchus, requiring biopsy forceps removal. The patient readily recovered with his symptoms thoroughly subsiding thereafter.
