Chronic obstructive pulmonary disease mismatch: a case of tracheal hamartoma

Objective: To demonstrate the diagnostic challenge of tracheal hamartoma in a patient with chronic obstructive pulmonary disease [COPD]

Clinical Presentation and Intervention: A 65-year-old man with COPD was admitted with sudden onset of asphyxia attacks related to the position of his body. Computerized tomography [CT] of the neck showed a soft tissue mass with calcification, which occluded more than two-thirds of the proximal part of the trachea. The tumor was completely removed, and histopathology confirmed hamartoma

Conclusion: This case report showed the detection of a primary tracheal tumor on CT. This finding enabled the correct diagnosis and led to appropriate treatment in the form of surgery

Sclerosing mesenteritis presenting as a pseudotumor of the greater omentum

Objective: The aim was to demonstrate a diagnostic challenge of sclerosing mesenteritis initially considered as liposarcoma

Clinical Presentation and Intervention: A 45-year-old man was admitted with a painful abdominal mass. Abdominal computed tomography demonstrated a well- demarcated tumor in his left hemiabdomen, with a large fat component and areas of soft tissue attenuation suggestive of liposarcoma. Intraoperative findings showed a tumor arising from the greater omentum. The tumor was completely removed, and histopathology confirmed a pseudotumorous type of sclerosing mesenteritis with dominant mesenteric lipodystrophy

Conclusion: This case showed that a pseudotumorous type of sclerosing mesenteritis should be considered in the differential diagnosis of the mesenteric tumors

Invasive Lobular Breast Cancer Presenting an Unusual Metastatic Pattern in the Form of Peritoneal and Rectal Metastases: A Case Report / 한국유방암학회지

Gastrointestinal metastases from invasive lobular breast cancer are uncommon with the stomach and small intestines being the most common metastatic sites. Peritoneal and rectal metastases are very rare and only rarely occur as the first manifestation of disease. We herein report the case of a 47-year-old woman who presented with abdominal carcinomatosis as a first sign of invasive lobular breast carcinoma (ILC). Identifying the most important immunohistochemical markers for ILC: gross cystic disease fluid protein 15, estrogen and progesterone receptors enabled a correct diagnosis. After a six year disease-free period, relapse occurred with severe obstruction due to rectal metastasis from lobular breast carcinoma. Since there was no widespread metastatic disease, surgery with concomitant hormonal therapy was performed.
