Endobronchial Solitary Papilloma

Abstract

A sixty-four year old male patient came to the emergency service with a haemoptysis complaint for which his postero-anterior chest X-Ray and computerized thorax tomography had no pathological findings. To find the origin of the haemoptysis, indirect laryngoscopy and endoscopy inspections were made. However, there was no pathology found on these inspections. At fiberoptic bronchoscopy a lobulated, white lesion approximately 0.5 cm in diameter was found at the entrance of left lower lobe anterior segment. The lesion was removed by forceps biopsy resection. The pathological inspection of this lesion resulted in a diagnosis of endobronchial papilloma. Examination of this biopsy with HPV DNA gave negative result. To plan his treatment, we examined the patient 2 weeks and 6 months later. He had no complaint and his bronchoscopic inspection had no pathological findings. We decided to examine him periodically. The endobronchial solitary papilloma is a rare benign tumor of the bronchus but we must be careful about smokers since this benign lesion may become malignanat. (Tur Toraks Der 2011; 12: 165-7)

Tracheal Papilloma Treated with Cryotherapy and Interferon-α: A Case Report and Review of the Literature

“…If the lesions are limited to a small part of the bronchi, photodynamic therapy, yttrium aluminum garnet (YAG), laser vaporisation, and electrocautery (snare) can be adequate in treatment [19]. In the case of solitary endobronchial papilloma reported by Yıldız et al [20], a small and localised lesion was resected totally with FOB and forceps biopsies. In two cases of endobronchial papilloma reported by Cömert et al [21], the lesions were resected by electrocautery snare.…”

A rare case: Endobronchial solitary mixed papilloma

“…Histopathologically, they are divided into three subtypes; squamous, glandular, and mixed type ( 6 ). Squamous cell papillomas are the most common papillomas and there are case reports in the literature ( 7 ). Among these cases, cases of squamous papilloma type with malignant transformation have been reported ( 3 ).…”

A Soft Tissue Aneurysmal Bone Cyst in Thoracic Cavity

“…The most important diagnostic feature is provided by the maturation pattern characterized by a central cellular area, an intermediate zone of osteoid formation, and a peripheral shell of a highly organized bone in cases of myositis ossificans (2,13,14). This zonal pattern and bone maturation towards the peripherals of the lesion are not seen in cases of ABCs, which can be used in the differential diagnosis (15). Another lesion to be taken into consideration in the differential diagnosis of soft tissue and bone ABCs is a giant cell tumor.…”

“…Histologically, the cystic spaces were filled with blood and the cyst walls were composed of bland spindle-shaped fibroblasts that grew in a fascicular or storiform pattern and were admixed with multi-nucleated osteoclast cells, hemosiderin-laden macrophages and trabeculary bones. Osteoid was seen focally near the capsule (12,15). Furthermore, CT and MRI are helpful in delineating the location and extent of the tumor and in identifying tumor tissues and local spread of a soft tissue mass.…”
