“…Mucous gland adenoma presenting as a peripheral lung mass is extremely rare. In the literature, only Karpathiou et al [2] and Lee et al [6] reported a case of mucous gland adenoma not related with a bronchus, but rather arising from lung parenchyma in a 59-yearold male and 68-year-old female, respectively. Here, we present another case of non-bronchial parenchymal mucous adenoma located peripherally.…”

Pulmoner mukus bezi adenomları, malign akciğer kitlelerinden ayırıcı tanısı yapılması gereken, nadir görülen benign tümörlerdir. Ayırıcı tanı atipik yerleşimlerde akciğer parankimi kaynaklı olanlar için özellikle önemlidir. Bu yazıda, yaklaşık iki yıldır öksürük ve balgam çıkarma yakınması olan 70 yaşında bir erkek hasta sunuldu. Göğüs bilgisayarlı tomografisinde akciğerin sol alt lobunda 1 cm'lik bir nodül görüldü. Tümör, mini torakotomi ve kama rezeksiyonu ile tamamen rezeke edildi ve frozen incelemesi için patoloji bölümüne gönderildi. Frozen sonucu benign olarak rapor edildi. Patolojik tanı mukus bezi adenomu idi. Hastada ameliyat sonrası komplikasyon gelişmedi ve tam iyileşme sağlandı. Pulmoner mukus adenomları nadiren akciğer parankiminden kaynaklanabilir ve periferik yerleşimli akciğer lezyonları olan hastalarda görülebilir. Anah tar söz cük ler: Bronşiyal neoplaziler; ayırıcı tanı; müsinöz adenoma cerrahisi; video-destekli göğüs cerrahisi.

“…The additional possibility that MGA entrapped the normal components of the bronchial wall, including cartilage, fat, and smooth muscle was unlikely because the growth of MGA was limited to the bronchial wall without involving the bronchial cartilage, and the amount of mesenchymal components was large considering the normal lung tissue. An exceptional case of MGA which had myxoid stroma with chondroid metaplasia has been reported . It resembled this case in predominant bronchial glands and cartilage at the first glance, but lacked other mesenchymal components including fat, bone, and smooth muscle …”

“…First, a collision tumor of mucous gland adenoma (MGA) and PH or MGA arising in PH were considered as salivary gland‐type tumors with myoepithelial differentiation arising in PH actually being reported . MGA is an extremely rare tumor, occurring in a lobar or segmental bronchus as a solitary, endobronchial polypoid nodule, and very few cases occur in the peripheral lung without connection to a bronchus . Microscopically, MGA is composed of glandular and tubulocystic or papillocystic mucous glands and is surrounded by a thin, fibrous capsule .…”

Pulmonary hamartoma (PH) is the most common benign lung tumor, comprising various amounts of mescenchymal components with entrapped epithelial components. We describe an unusual case of PH in the left lower lung lobe of a 60-year-old female. The tumor was 9 × 9 mm in size, light brown, weakly glistening, and microscopically found to be composed of well-developed epithelial and mesenchymal components without atypia. Both components were intermingled but without apparent transition. Epithelial components were occupied by predominant bronchial mucous glands. Serous glands, entrapped bronchioles, and clefts lined by respiratory epithelium were also apparent. Mesenchymal components including cartilage and fat were scattered, and swirling smooth muscle fascicles were interlaced with epithelial components. Collision tumor or other biphasic tumors were unlikely, and hyperplastic change in bronchial glands as in the rare conditions of intraoral minor salivary glands and epithelial entrapments by PH may explain these interesting histological findings. It is important to be aware of the possibility that a large number of bronchial mucous glands may be noted in the peripheral lung, and not to mistake this for other malignancies.
