Hydatic Cyst

Hepatoid adenocarcinoma (HAC) is a very rare type of extrahepatic adenocarcinoma which has a clinicopathologic and morphologic similarity to hepatocellular carcinoma (HCC). Although it is not common, it can be seen in organs other than the liver. The correct diagnosis can be a challenge because of its clinically similarity to HCC and the diagnosis is usually achieved by pathological examination following the surgery. We present a 48-year-old woman who was following with the diagnosis of stage 5 hepatic hydatic cyst. In her routine blood examinations, her alpha feta protein level was found higher than normal and her abdominal computed tomography and magnetic resonance findings did not reveal any pathological findings rather than hepatic hydatic cysts. There was a high activity of FDG on PET CT in the hepatic region so we performed a right lateral hepatectomy to the patient and final pathology was adrenal hepatoid adenocarcinoma. In this paper we aimed to present a rare case of hepatoid carcinoma of the adrenal gland.

Hemangioma are rare tumor originating from the pericytes, the contractile cells that surround capillaries. This tumor arises from pericapillary cells or pericytes of Zimmerman and can occur anywhere where capillaries are found . Howeverhemangiopericytoma develops mainly in the lower extremities, retroperitoneum or pelvis. The recommended treatment for a hemangiopericytoma is wide excision. Since many benign and malignant diseases occur in the area surrounding the anus, recognizing the presence of this malignant tumor in the presacral space is important in order to avoid inappropriate surgery such as piecemeal excision. We describe a rare case of a hemangiopericytoma in the presacral space. With posterior approach the tumour was completely removed. Pathological examination includingimmunohistologicalstains was consistent with a hemangiopericytoma.

Abstract Background A 52-year-old woman presented with shortness of breath and cough. An endobronchial sialolipoma was found at the left entrance of the main bronchus. Sialolipoma is an exceedingly rare type of lipoma reported of the minor salivary glands, especially within the bronchus. Case presentation A 52-year-old woman presented with shortness of breath and cough with 6 months´ evolution. Endobronchial endoscopy revealed a tumour at the left entrance of the main bronchus. The entire removal of the tumour was removed using a cryoprobe device. Pathological examination showed a tumour consistent with the diagnosis of sialolipoma due to the presence of mature adipose cells blended with acinar, ductal, basal, and myoepithelial cells. The patient had a favourable outcome. Conclusion The infrequent tracheobronchial presentation of this tumour can be challenging for correct diagnosis.

Ameloblastic carcinoma is a rare type of ameloblastoma that has received little mention in the literature. While a number of cases have been published over many years, no institution has been able to produce a substantial case series. Ameloblastic carcinoma originates in the embryonic tooth components. It is believed to be an aggressive tumor that can metastasize; once metastasis occurs, the prognosis tends to be poor. Ameloblastic carcinoma is primarily a surgical condition that is best treated with resection; there has been little indication that other modalities are helpful. We present the case of a 40-year-old woman who was found to have a mandibular lesion by a dentist. After surgical resection, the tumor was found to be an ameloblastic carcinoma. The patient recovered without complication, and she was recurrence-free 18 months postoperatively. We also briefly review the available literature on the natural history of and management options for this rare tumor.

Abstract Background Thymic carcinoid is one of an extremely rare type of malignant neuroendocrine tumor with a poor prognosis. Invasion of thymic carcinoid to other organs could lead to devastating consequences. It has been reported that thymic carcinoid mainly invaded to the pleura, lungs, liver, pancreas and bone, while rarely to the cardiac, especially to the ventricle. Case presentation A 53-year-old man presented with gastrointestinal symptoms and persistent pericardial effusion. Multiple imaging tools, including chest computed tomography (CT), magnetic resonance imaging (MRI), 18F-Fluorodeoxyglucose positron emission tomography/CT (18F-FDG PET/CT) showed a malignant neoplasm arising from the thymus invading into the biventricular myocardium, pericardium, and left superior pulmonary veins. The tumor was finally diagnosed as a thymic carcinoid through pathological examination. Conclusion This is a rare case of thymic carcinoid invading the ventricular myocardium, which presented as subacute heart failure. The observations in this case would be useful for differential diagnosis of primary heart disease and invasion of heart due to thymic carcinoid.

Introduction. Mechanical conjunctivitis is a rare form of eye surface inflammatory condition. One of its types, a mucus fishing syndrome, leads to a chronic eye surface trauma. Purpose. To review the available literature data on the mechanical conjunctivitis prevalence, and to describe the diagnosis and treatment methods of its rare type, the mucus fishing syndrome. Materials and methods. The article describes the case of the mucus fishing syndrome development in a patient suffering from this type of mechanical conjunctivitis for about 3 years. Results. The correct diagnosis was not established in our patient for a long period of time that is why an improper treatment had been prescribed, which led to complications and to the need for surgical treatment. Conclusions. The prevalence of mechanical conjunctivitis is low, and in the available literature, there are only 4 publications on the topic. The mucus fishing syndrome should be treated in cooperation with a psychiatrist, since the usual use of topical reparative and lubricating therapy is not enough.

Tuberculous prostatitis is an uncommon form of tuberculosis infection. It is commonly seen in immunocompromised patients and in those of middle or advanced age. The diagnosis is often not straight forward due to the nature of its presentation. We report a case of tuberculous prostatitis in a young, healthy and immunocompetent patient, who initially presented with respiratory features, followed by episodes of seizures and testicular swelling. He was finally diagnosed with tuberculous prostatitis after prostatic biopsy. This case illustrates that in a high TB prevalence environment, when symptoms warrant, there should be a high clinical suspicion coupled with a thorough approach in order to arrive at a correct diagnosis of TB prostatitis.

Background:18F-fluorodeoxyglucose positron emission tomography integrated with computed tomography (18-F-FDG-PET/CT) is getting wide consensus in the diagnosis and staging of neoplastic disorders and represents a useful tool in the assessment of various inflammatory conditions. </P><P> Discussion: Sarcoidosis is an uncommon disease characterized by the systemic formation of noncaseating granulomas. Lungs are the sites most often affected, and investigation with high resolution computed tomography and biopsy is essential to achieve a correct diagnosis. 18-F-FDGPET/ CT is effective in the assessment of pulmonary sarcoidosis by demonstrating pulmonary and extrathoracic involvement and findings correlate well with pulmonary function in patients affected.Conclusion:This review would illustrate the usefulness and limits of 18-F-FDG-PET/CT in the assessment of pulmonary sarcoidosis.

Abstract Background Erdheim-Chester disease (ECD) is a rare, idiopathic, systemic non-Langerhans cell histiocytosis involving long bone and visceral organs. Central nervous system (CNS) involvement is uncommon and most cases develop as a part of systemic disease. We present a rare case of variant ECD as an isolated intramedullary tumor. Case presentation A 75-year-old female patient with a medical history of diabetes and hypertension presented with sudden-onset flaccid paraparesis for 1 day. Neurological examination revealed grade 2–3 weakness in both legs, decreased deep tendon reflex, loss of anal tone, and numbness below T4. Leg weakness deteriorated to G1 before surgery. Preoperative magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) showed an intramedullary mass lesion at T2-T4 with no systemic lesion, which was heterogeneous enhancement pattern with cord swelling and edema from C7 to T6. Gross total removal was achieved for the white-gray-colored and soft-natured intramedullary mass lesion with an ill-defined boundary. Histological finding revealed benign histiocytic proliferation with foamy histiocytes and uniform nuclei. We concluded it as an isolated intramedullary ECD. The patient showed self-standing and walkable at 18-month with no evidence of recurrence and new lesion on spine MRI and whole-body FDG-PET/CT until sudden occurrence of unknown originated thoracic cord infarction. Conclusions We experienced an extremely rare case of isolated intramedullary ECD, which was controlled by surgical resection with no adjuvant therapy. Histological examination is the most important for final diagnosis, and careful serial follow-up after surgical resection is required to identify the recurrence and progression to systemic disease.
