Abstract PDF: A 50-year-old female patient presented with anorexia and weight loss. Pelvic computed tomography revealed a 12.5 x 7.3 cm heterogeneous mass in the left ovary. About 30% of the tumor was occupied by a mature cystic teratoma. The remaining solid portion was composed of fibrous and histiocytic elements, arranged in storiform patterns admixed with bizarre giant cells. The mitotic index was 8 per 10 high power fields, including atypical mitoses. The only immunopositivity was for vimentin. The tumor was diagnosed as a malignant fibrous histiocytoma arising in a mature cystic teratoma. To the best of our knowledge, this is only the third such case in the English language literature.

Complex Bronchopulmonary Foregut Malformation: Extralobar Pulmonary Sequestration Communicating with an Esophageal Duplication Cyst: A Case Report.: Soyoung Im, Sun Mi Lee, Ji Han Jung, Jinyoung Yoo, Kyu Do Cho, Seok Jin Kang, Kyo Young Lee; Korean J Pathol. 2010;44(2):207-210.; DOI: https://doi.org/10.4132/KoreanJPathol.2010.44.2.207

We report here on a case of a rare, complex bronchopulmonary foregut malformation (BPFM) that was composed of an extralobar pulmonary sequestration communicating with an esophageal duplication cyst. A 33-year-old female presented with an incidentally detected chest mass. The computed tomography revealed a 7.5 x 4.0 cm sized heterogeneous, solid and cystic lesion in the right superior mediastinum. Surgical resection demonstrated the solid portion to be isolated lung tissue invested in its own pleura. A unilocular cyst was communicating with the bronchus of the sequestrated lung, and microscopically the cyst was lined by squamous epithelium overlying the thick layers of smooth muscle. This case is important for understanding the spectrum of BPFMs and for differentiating a mediastinal mass, especially one at the unusual location.

Abstract PDF: Malignancies in congenital cystic adenomatoid malformations (CCAMs) of the lung are rare. We report a 41-year-old male patient with a pulmonary cystic lesion suspicious for CCAM, unrecognized until the patient was 40 years of age, and which subsequently became more consolidated during the interval between initial presentation and surgery. Microscopic examination of the resected specimen revealed features of type 1 CCAM with a mucinous adenocarcinoma, metastatic to the mediastinal lymph nodes. This case illustrates the importance of prompt surgical resection for all suspected CCAMs, especially those discovered in adulthood.

Abstract PDF: Inflammatory myofibroblastic tumor (IMT), normally referred to as inflammatory pseudotumor, is a fairly rare condition. Fine needle aspiration cytology (FNAC) of IMT has only rarely been reported. Here, we describe one such case of pulmonary inflammatory myofibroblastic tumor. A 30-year-old man presented with a 2.8cm-sized mass in his lung. Chest CT revealed a well defined, poorly enhancing mass. FNAC showed some fascicular or swirled clusters of spindle cells, admixed with occasional inflammatory cells and foamy histiocytes. The majority of the tumor cells evidenced bland, elongated nuclei, but infrequent pleomorphic nuclei. Some of the tumor cells evidenced nuclear grooves and intranuclear inclusions. Although the cytological differentiation of IMT from malignant lesions is not immensely problematic, due to the general paucity of cytological and nuclear atypia, a definite cytological diagnosis of IMT cannot be rendered simply by FNAC. Therefore, a diagnosis of IMT may be suggested via exclusive diagnosis.
