Tracheopbronchopatia osteochondroplastica – a case presentation

Narrowing of the lower respiratory tract is a rare pathology. It may be associated with pathologies of the primary respiratory system or connective tissue diseases (systemic scleroderma, granulomatosis with polyangiitis, relapsing polychondritis). It can lead to non-specific clinical symptoms. We present an interesting case of a 52-year old patient with a history of several months’ dyspnea. Imaging tests revealed significant stenosis of the trachea and the left main bronchus. Tracheobronchopatia osteochondroplastica was diagnosed. Moreover, we carry out the differential diagnosis of the above pathology

Acute hypersensitivity pneumonitis associated with mushroom worker’s lung – a case report

Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis is a non-IgE mediated allergic reaction to inhalation of an allergen. There are more than 200 allergens known to cause this condition, but the list of antigens responsible for the development of HP is constantly expanded. Dangerous agents are usually inhaled at the workplace, so we may distinguish the following patients at risk of HP: farmers, pigeon breeders, mushroom workers, cheese employees or even malt workers. Mushroom worker's lung (MWL) has been described in workers exposed to mushroom spores or to inhaled antigens from compost (mostly thermophilic actinomycetes)

Malignant peripheral nerve sheath tumor in a patient without neurofibromatosis 1 (NF1): a rare case of primary lung location

We present a rare case of a patient operated due to a lung tumor, which was ultimately diagnosed as malignant peripherial nerve sheath tumor (MPNST). MPNSTs are rare tumors of soft tissue with mesenchymal origin. The World Health Organization has distinguished this group in order to unify terms in mesenchymal heterogeneous malignant tumors, e.g. neurofibrosarcomas, malignant schwannomas and malignant neurilemmoma [1]. They can occur as a result of neoplastic expansion of peripheral nerves’ branches, peripheral nerve fibers’ sheaths or Schwann cells, although many researchers believe that these tumors can derive not only from one, but several cell lines. MPNSTs are very rare in thorax, where they show aggressive pattern of growth [2] and stem from pleural cells rather than lung tissue.
