Wedge Biopsy

Abstract Context.—Frozen section of lung tissue is performed to guide the surgeon in subsequent therapy. Design.—Practical experience in frozen section of the lung was reviewed in the medical literature and from the records of several academic hospitals. Results.—Most frozen sections of the lung are performed for evaluation of a solitary nodule, a mass, or the surgical margins of a resection. Frozen section may also be used to assess the adequacy of a lung wedge biopsy taken for later diagnosis of a condition. Conclusion.—The pathologic evaluation of intraoperative pulmonary lesions is indicated for the differential diagnosis of pulmonary nodules and masses, both neoplastic and nonneoplastic, surgical resection margins, and mediastinal lymph nodes. The most worrisome pitfalls involve differentiating benign reactive atypia from malignancy on frozen section.

Abstract This report describes a benign myoepithelioma of the lung that occurred in a 60-year-old woman. The patient had experienced hoarseness for 6 weeks, and a computed tomographic scan showed a nodule of approximately 2 cm in diameter at the peripheral portion of her right upper lung. Positron emission tomography showed no uptake of F-18 fluorodeoxyglucose in the nodule. Wedge biopsy of the lesion showed benign spindle cells arranged in a whorled pattern. The cells were positive for both cytokeratin and smooth muscle actin, which corresponded to the presence of tonofilaments and myofilaments that were identified ultrastructurally. The features of the present case of benign myoepithelioma that differ from features of previously reported benign and malignant cases of myoepithelioma in the lung are discussed in the report.

Peripheral Nerve Sheath Tumour

Leiomyoma, a benign monoclonal tumour, is very rarely found in extrauterine sites, especially in the vulval region. Histopathology of the soft tissue tumours affecting this region is similar and immunohistochemistry (IHC) may be essential to confirm the diagnosis. We report a case of a 63-year-old postmenopausal woman who presented with a recurrent vulval mass involving the clitoris and left labia majora with suspected urethral involvement. Although the wedge biopsy was reported as peripheral nerve sheath tumour, staining with smooth muscle actin clinched the diagnosis of leiomyoma, highlighting the importance of IHC for diagnosis.

Pleural Involvement

A 47-year-old woman presented with spontaneous right side pneumothorax. Image studies showed consolidations and reticular opacities involving the pleural and subpleural regions of bilateral lungs. Wedge biopsy specimens of right upper, middle and lower lobes showed fibrosis of the visceral pleura and subpleural area in all three lobes, more significant in the upper lobe. Elastic Van Gieson stain showed a pattern of alveolar septal elastosis with intra-alveolar fibrosis. The clinical presentation and pathological findings are compatible with pleuroparenchymal fibroelastosis, a rare and distinct type of interstitial lung disease. This entity is different from usual interstitial pneumonia by its relationship to pleura, upper lobe predominance and temporal homogeneity. It is different from non-specific interstitial pneumonia by its pleural involvement and scanty inflammatory cell infiltration. Pleuroparenchymal fibroelastosis is a slowly progressive disease; about half of the patients die in 10 years. No curative treatment is available at present time.

Wedge Biopsy

A 70-year-old woman was referred to our hospital from primary health centre with complaints of pain in the abdomen, swelling and discharging sinus in the right hypochondrium since 2 years. She had received anti-tubercular treatment for 18 months as the wedge biopsy of the sinus tract suggested granulomatous lesion. As the symptoms did not subside she was referred to our hospital. Her blood investigation reports at our hospital were normal. Ultrasound of the abdomen suggested cholelithiasis with normal common bile duct. CT fistulogram findings were diagnostic of cholecystocutaneous fistula (CCCF). She underwent laparoscopic cholecystectomy and excision of the sinus tract. Postoperative recovery was uneventful. Indiscriminate usage of anti-tubercular drugs should be discouraged and possibility of CCCF should be considered in patients presenting with discharging sinus in the anterior abdominal wall. CT fistulogram is helpful in making diagnosis of CCCF. Cholecystectomy with excision of the sinus tract is the treatment of choice.
