The AIRP faculty identifies the best cases from each organ syst...
A 23-year-old man presented with difficulty walking and leg pain and numbness. MRI revealed a cystic mass at Th11-12 and a pineal-region tumour. The patient underwent surgery to resect the thoracic-level mass. The tumour adhered strongly to the neural tissue and could only be partially resected. On pathological examination, the resected tumour was diagnosed as a mature teratoma. The tumour regrew and disseminated within 3 months after resection. Both the spinal cord tumour and the tumour in the pineal reg...
Malignant transformations of ovarian mature cystic teratomas (MCTs) occur rarely, especially in young women. Although it is extremely difficult to diagnose them, serum tumor marker level testing in combination with the use of imaging techniques may be useful in preoperative diagnosis.
A perforating mediastinal mature teratoma can cause severe inflammation and adhesion; therefore, open surgery is usually performed. Asymptomatic perforation involving a teratoma is very rare. Complete thoracoscopic surgery is often difficult because of inflammation associated with perforation and the frequently large size of a mediastinal mature teratoma. We report a rare case of an asymptomatic perforating mediastinal mature teratoma successfully treated with complete thoracoscopic surgery.
We developed a radiologic-risk signature (RRS) that serves as a surrogate for the pathologic status of prostate cancer (PCA) and investigated its ability to predict disease-free survival.
Malignant melanoma (MM) arising in ovarian cystic teratoma (OCT) is a rare disease with poor prognosis. Recently, immune checkpoint inhibitors of cytotoxic T-lymphocyte-associated antigen 4 (CTLA4) and programmed death 1 (PD-1) have shown promising results in MM. Herein we report a case of MM arising in OCT.
Ovarian teratomas potentially demonstrate a wide range of tissue elements including central nervous system differentiation. The latter can include cerebellar tissue, which in our experience remains an under-recognized phenomenon. In the current study we present a review of 6 ovarian teratomas including 4 mature cystic teratomas and 2 immature teratomas showing cerebellar differentiation. Two cases were seen in consultation because the cerebellar elements were initially misinterpreted as immature teratomas. ...
Primary lung tumors in children are rare, with a narrow range of diagnostic considerations. However, the overlapping imaging appearances of these tumors necessitate attention to key discriminating imaging and pathologic features. In the neonate and infant, the important considerations include pleuropulmonary blastoma (PPB), infantile fibrosarcoma, and fetal lung interstitial tumor. Among these tumors, imaging findings such as air-filled cysts in type 1 PPB and homogeneously low attenuation of fetal lung int...
Sacrococcygealteratoma is very rare in adults with only few cases reported in literature. It is a slow growing benign cystic tumor with 1-2% chance for malignant transformation and may attain a huge size causing pressure effect on pelvic and intra-abdominal organs. When grows caudally, it causes discomfort, skin excoriation and cosmetic disfigurement.
The purpose of this article is to investigate the radiologic and clinicopathologic findings of mucocelelike lesions (MLLs) and the rate of pathologic upgrade with factors predicting it.
Inflammation of the appendix is one of the most common conditions requiring emergent surgical intervention. Computed tomography commonly demonstrates a dilated appendix with adjacent inflammation. Traditionally, luminal obstruction of the appendix has been thought to be the primary etiology of appendicitis. However, current evidence suggests that etiology of appendicitis is multifactorial and can involve a number of different pathogenic pathways. Here we present a case of acute eosinophilic appendicitis wit...
Mature ovarian teratomas are common in children. These well-differentiated tumors are typically confined to the ovary. In rare cases, they can rupture leading to granulomatous peritonitis that mimics carcinomatosis. Ovarian tumors with peritoneal/omental implants suggest malignant pathology with different prognosis.
Primary intracranial teratomas account for
Nephroblastoma (NB) is a malignant embryonal neoplasm derived from nephrogenic blastemal cells. NB usually forms a solid mass, but in extremely rare cases, it may show cystic changes.
Mature ovarian teratoma is the most frequent benign tumor in premenopausal women. It is usually asymptomatic but complications are possible such as adnexal torsion, infection, malignant transformation or cystic rupture. The latter can be spontaneous or more often occurs during surgery of excision of dermoid cyst. It can rarely result in chemical peritonitis, which is due to the irritation of the peritoneal serosa by the aseptic content of the tumour. We report the case of a patient who undrewent an emergenc...
Two patients were admitted to our department because of recent aggravation of claudication in the leg, which was exacerbated by walking. They were diagnosed as having a Baker cyst or acute thrombosis in the popliteal fossa at another hospital. There was no evidence of ischemia, and the ankle brachial index was normal. Computed tomography and magnetic resonance imaging were performed, revealing a cystic mass of the popliteal artery (PA). Intraoperatively, the cystic lesion was found within the adventitia of ...
The problems associated with the pathologic distinction of primary ovarian mucinous tumors from their metastatic counterparts are well-recognized. Herein, we systematically evaluate a variety of gross parameters to determine the combination of features that most optimally separate primary from secondary mucinous ovarian tumors, and to address the tumor types that are most frequently associated with exceptions. 129 consecutive mucinous tumors involving the ovary formed the study set, including 61 primary muc...
Recent molecular re-evaluation of Echinococcus granulosus, which causes cystic echinococcosis (CE), has revealed that it is not a single species, but instead consists of 5 cryptic species. Among them, E. granulosus (dog-sheep strain) is predominant (75%) followed by Echinococcus canadensis (22%). The major affected organs, in humans, are the liver (88%) and lungs (11%). Primary cerebral CE comprises less than 1% of all cases. As cerebral CE cases are rare, there are few reports with molecular confirmation o...
Tracheal adenoid cystic carcinoma (ACC) is rare and accounts for
There are three major pathologic patterns of pulmonary fibrosis; usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP) and airway-centered fibrosis (ACF). These pathologic patterns correspond with radiographic patterns of UIP, NSIP, and chronic hypersensitivity pneumonitis (CHP). Previous studies have demonstrated that the radiologic diagnosis is correct approximately 50% of the time for these fibrotic lung diseases. Understanding the microscopic pathologic patterns that are recapitu...
Radiologic severity may predict adverse outcomes after lower respiratory tract infection (LRI). However, few studies have quantified radiologic severity of LRIs. We sought to evaluate whether a semi-quantitative scoring tool, the Radiologic Severity Index (RSI), predicted mortality after parainfluenza virus (PIV)-associated LRI.
We describe a 24-year-old man with a cystic hygroma of the left side of the lower neck that led to sudden death. Cystic hygroma (cystic lymphangioma) is a congenital malformation of the lymphatic system. The patient, who had a tracheostomy because of airway obstruction from the cystic hygroma, was found dead with his tracheostomy tube on the floor next to him. Complications of cystic hygroma include infiltration of the neck causing airway obstruction, dysphagia, pain, and obstructive sleep apnea.
Individuals diagnosed with cystic fibrosis (CF) as adults represent a growing sub-population of CF cases but there are limited studies describing their characteristics and prognosis.
Nasopharyngeal carcinoma (NPC) with cystic liver metastases is so rarely observed that there are only three cases reported in the published literature.
Granulomatous mastitis is an uncommon inflammatory disease that typically presents with painful breast lesions. Recent publications have brought to light a specific subset of granulomatous mastitis patients with a distinct histological pattern of disease termed, "cystic neutrophilic granulomatous mastitis" (CNGM). Although many cases of granulomatous lobular mastitis have been thought to be idiopathic, this rare subset of an uncommon disease has been linked to infections with Corynebacterium species. Herein...
