“…There were microscopic foreign materials scattered in the lesion, which were phagocytosed by host cells. Although macrophages can phagocytose foreign bodies [7], non-absorbable surgical materials might be retained for a long time in the body because of inability to degrade these materials [8,9]. We were unable to identify the substance directly due to scattered and tiny samples obtained.…”

A foreign body granuloma is a mass lesion consisting of a foreign body with host reaction. Its diagnosis is not always easy in respect of its similarity to soft tissue sarcoma. The most common foreign body is surgical sponge which can be detectable macroscopically. We present a foreign body granuloma in the left buttock caused by microscopic surgical materials that developed into a large lesion. An 80-year-old man with a history of surgery for dislocation of the left hip 20 years earlier, presented with a slowly growing mass that had expanded rapidly over the preceding 2 months. Histological examination revealed organizing granulation tissue surrounding the scattered foreign materials. One should be aware of foreign body granuloma at previously operated sites even without a retained macroscopic gauze sponge.

“…The most likely differential diagnosis for postoperative shadows around a surgical stump is recurrence of the resected malignancy, although infection, granuloma and inflammatory lesion are other differential diagnoses. Suture granuloma of the stump has been reported [1–3]. Absorbable or monofilament sutures should be used to prevent suture granuloma.…”

Pulmonary Staple-Stump Granuloma After Segmentectomy: Two Case Reports and Comparison with Cases of Stump Recurrence

Case series Patient: Male, 70 • Female, 60 Final Diagnosis: Staple stump granuloma Symptoms: Abnormal shadow on computed tomography Medication: — Clinical Procedure: — Specialty: Surgery Objective: Rare disease Background: Correctly diagnosing a staple-line mass after pulmonary resection for lung malignant tumor can be difficult. Differential diagnoses of recurrence, infectious mass, granuloma, and so on must be considered, despite their rarity. We report two cases of pulmonary staple-stump granuloma after segmentectomy for lung cancer. Case Reports: Case 1 involved a 70-year-old man with small nodule in the left upper lobe identified on computed tomography (CT). Video-assisted thoracoscopic (VATS) left upper division segmentectomy was performed. Histopathological examination revealed squamous carcinoma. Follow-up CT 1 year postoperatively showed a shadow at the staple-stump, with growth evident later. CT-guided biopsy found no malignancy. However, complete left upper lobectomy was performed because of the gradually enlarging lesion. Histopathological examination revealed epithelioid granuloma. Case 2 involved a 60-year-old with suspected lung cancer in the right upper lobe. VATS right upper division segmentectomy (S2) was performed. CT at 30 months postoperatively showed a shadow at the staple line, with subsequent growth. VATS right upper lobectomy was performed. Intraoperative rapid diagnosis revealed epithelioid granuloma. These two cases were compared with five cases of staple-stump recurrence in our institution. All cases of recurrence grew concentrically or radially from the staple line with the mass surrounding the staple line. On the other hand, cases of granuloma extended along the long axis of the staple line, and 3-dimensional CT (3DCT) may help to understand the morphology. Conclusions: Although preoperative differentiation of staple-line granuloma is difficult and pathological diagnosis is important, characteristic radiologic features and 3DCT may facilitate diagnosis.
