Although very rare, cystic adenoid carcinoma (CAC) should be considered as a differential diagnosis for any lung tumor arising from the bronchial glands. The diagnosis is typically confirmed through histological examination, and treatment is primarily based on surgical intervention. In this report, we present the case of an 82-year-old male with primary CAC of the lung.

Primary pulmonary lymphoma (PCL) is rare and represents only 0.5-1% of the malignant lung tumour. Pulmonary MALT lymphoma is the most common histological aspect. The pathophysiological mechanism remains poorly known, unlike other locations of MALT lymphoma, no pathogen has so far been associated with the lung localization of the disease. It is characterized by slow evolution and atypical clinical presentation which delays diagnosis. The form «pneumonic» on the imaging allows to evoke the diagnosis while the confirmation is based on the immunohistochemical study which detects the presence of positive CD20 cell. Therapeutic options include surveillance of indolent types of LPP, surgery in localized tumors, chemotherapy in diffuse forms. We report two observations of diagnosed pulmonary MALT lymphoma on a scanno-guided bronchial and pulmonary biopsy.

Neurofibromatosis type 1 (NF1) is an autosomal dominant condition characterized by café-au-lait spots, cutaneous neurofibromas, axillary and inguinal freckling, and iris Lisch nodules; however, the presentations vary greatly, even within families. NF1 is also a recognized risk factor for the development of malignancy particularly malignant peripheral nerve sheath tumors (MPNST), optic gliomas, other gliomas, and leukemia. Nevertheless, the occurrence of lung cancer in a patient with neurofibromatosis type 1 is a rare phenomenon.Here we present a case of neuroendocrine tumor in a patient with neurofibromatosis type 1, highlighting the association between the two diseases. This case report also aimed to raise awareness of possible malignancies in patients with neurofibromatosis type 1.

The most common tumors causing pleural metastasis in women are gynecological cancers, with breast cancer at the top of the list. However, the revelation of the latter by pleural effusion is rare. We report the case of a 61-year-old woman, with a history of well-controlled asthma since the age of 20, who was initially consulted for dyspnea stage III of the Modified Medical Research Council score (mMRC). Chest X-ray showed moderate bilateral pleural effusion. The pleural biopsy concluded with a pleural metastasis of breast carcinoma.
