Endobronchial epithelial papilloma associated with a foreign body

Endobronchial Glandular Papilloma With Atypical Histologic Characteristics: A Case Report and Literature Review

Papilloma of the lung is a rare benign entity and can be solitary or multiple. Solitary papilloma is subclassified into three categories: squamous papilloma, glandular papilloma, and mixed squamous and glandular papilloma. Glandular papilloma is the rarest subtype among them and occurs mostly in the sixth decade without any relation to smoking, syndrome, or infection. Histology is characterized by mixture of pseudostratified, columnar, nonciliated, mucinous epithelium-lined papillary fronds without any mitoses, necrosis, or atypia. The differential diagnosis can be broad depending upon the histologic features present in a particular case and may include both benign and malignant entities. We present here a patient with glandular endobronchial papilloma showing unusual clinical history and atypical histologic features, which required extensive immunohistochemical evaluation to establish a final diagnosis.

Respiratory papillomas

Papillomas are known to occur in the lower respiratory tract. They are however, rare compared to their occurrence in the upper respiratory tract. These are generally exophytic tumors in the more proximal upper airways however cases with more distal location with an inverted growth pattern have also been described in the literature. These can be solitary or multiple and multifocality associated with multiple papillomas in the upper respiratory/aerodigestive tract. The four major types of respiratory papillomas are (1) Recurrent respiratory papillomas, (2) solitary squamous papillomas, (3) solitary glandular papillomas, (4) mixed papillomas. We review the incidence, etiopathology, diagnosis, and possible treatment modalities and algorithms for these respiratory papillomas.

One Lung Wheezing due to Endobronchial Solitary Papilloma

A 55-year-old man was referred to our hospital due to intolerant severe short of breathing and persistent cough for two hours. He had similar attacks in the past two years which were treated with bronchodilators. Computed tomography revealed endobronchial mass, which was endoscopically resected by laser. Histology revealed benign squamous papilloma. In this paper we will deal with the various nonspecific clinical presentations, etiopathology, predisposing factors, and diagnosing tests of these benign tumors, especially the important role of computed tomography.

Solitary squamous cell papilloma of the trachea

We report a case of solitary squamous cell papilloma of the trachea and review 55 other previously reported cases. A 69-year-old man was admitted to our hospital with hemoptysis. Bronchoscopy demonstrated a papillomatous tumor diagnosed as a squamous cell papilloma. A circumferential resection of the trachea with end-to-end anastomosis was carried out. The patient's postoperative course was uneventful. From the review, there seems to be no considerable difference in the prognoses between the endoscopically and surgically managed groups. The following indications for surgical management of solitary tracheobronchial papilloma are proposed: (1) wide-based tumor, (2) poorly visualized tumor by endoscopy, (3) suspicion of malignant tumor, and (4) patients not suitable for long-term follow-up.

Retained endobronchial foreign body removal facilitated by steroid therapy of an obstructing, inflammatory polyp

Oral and topical steroids were used to induce regression in an inflammatory, obstructing endobronchial polyp caused by a retained foreign body. The FB (a peanut half), which had been present for over six months, was then able to be easily and bloodlessly retrieved with fiberoptic bronchoscopy.
