Symptomatic sclerosing haemangioma: a rare case of solitary pulmonary nodule in a young girl

Unexpected diagnosis of multiple sclerosing pneumocytomas in a patient with chondrosarcoma of the hand

Sclerosing pneumocytomas are rare, benign pulmonary neoplasms that predominantly affect Asian female patients in the age category of 40-70 years, mostly non-smokers. We report on a 72-year-old Caucasian woman with chondrosarcoma of the hand who developed multiple bilateral progressive lung nodules suspicious of lung metastases. Staged lung resections were performed, and pathological diagnosis was confirmed by immunohistochemical analysis of the resected specimens. Next-generation sequencing (NGS) was used to detect gene mutations. Immunohistochemistry demonstrated sclerosing pneumocytomas, and NGS showed an IDH1 mutation. Eventually, the patient developed lung metastases for which rethoracotomy was performed. The differentiation of sclerosing pneumocytoma from lung cancer is a diagnostic challenge, and sclerosing pneumocytoma should be considered in the differential diagnosis of pulmonary nodules. Gene mutation analysis does not always show classical and common mutations, which should be kept in mind when interpreting its results.

Co-occurrence of bronchial papilloma and pulmonary sclerosing hemangioma in a male

INTRODUCTION

Bronchial papilloma and pulmonary sclerosing hemangioma (PSH) are rare tumors. The development of PSH combined with bronchial papilloma in lung is extremely rare. We herein presented a case of the co-occurrence of bronchial papilloma and PSH in a male.

CASE DESCRIPTION

A 48-year-old man was referred to our department for further treatment of the productive purulent cough and fever. After bronchoscopy, the biopsy of the specimen showed a bronchial papilloma in the lumen of posterior segment of the right upper lobar bronchus. For computed tomography demonstrated a focal lesion with an air bubble in the posterior segment of the right upper lobe, a lobectomy was performed and PSH was diagnosed.

DISCUSSION

The report emphasizes the fact that even though some of bronchial papilloma and PSH may have a low prevalence, nonetheless, the low prevalence of both diseases in a male has meant that it has not been possible to explore the depth of association between them.

CONCLUSIONS

The paper reports a case of PSH in a male suffering from bronchial papilloma which is the exceptional concurrence of these two extremely infrequent events.
