A 32-year-old woman with an uneventful antenatal period underwent a caesarean section for breech presentation. At laparotomy, there were multiple yellowish elastic nodules distributed along the parietal peritoneal surface, totalling over 30 lesions and worrying the surgical team. The conclusive diagnosis of peritoneal deciduosis was supported by pathological analysis (histology ...

Background: A simple subcutaneous lesion such as an epidermoid cyst can present a challenge when located in the nasal tip, as regards aesthetic surgical management. Even when performed parallel to relaxed skin tension lines, a direct transcutaneous incision (commonly used for epidermoid cyst removal) distorts the nasal tip subunit, resulting ...

Schwannoma is an intraoral rare, benign neoplasm arising from and consisting solely of Schwann cells. Its etiology is unknown. It presents as a solitary, slow growing, smooth surfaced, generally asymptomatic firm mass. Schwannomas commonly occur between 30 and 50 years. It is relatively uncommon, although a quarter of all Schwannoma's ...

The cyst-theca relationship of Protoperidinium fukuyoi n. sp. (Dinoflagellata, Protoperidiniaceae) is established by incubating resting cysts from estuarine sediments off southern Vancouver Island, British Columbia, Canada, and San Pedro Harbor, California, USA. The cysts have a brown-coloured wall, and are characterized by a saphopylic archeopyle comprising three apical plates, the ...

Sarcoidosis is a multi-system, granulomatous disease, which affects the skin in approximately 20 to 30 percent of cases. Recognition of cutaneous sarcoidosis can be challenging because of the wide range of skin lesion morphologies. Ulcerative sarcoidosis is uncommon. We present a 35-year-old woman with pretibial ulcerative sarcoidosis, indurated tattoos, and ...

Endoscopic ultrasonography (EUS) has become an indispensable diagnostic procedure pairing endoscopy with transluminal high frequency ultrasonography. EUS provides images with a high resolution such that the depth of tumor invasion can be accurately determined. It also sees lesions outside of gastrointestinal tract, particularly those in pancreas, biliary system and periluminal ...

Sclerosing cholangitis (SC) is one of the lesions frequently seen in IgG4-related systemic diseases, causing biliary stricture and mimicking bile duct carcinoma and primary sclerosing cholangitis (PSC). Although it often accompanies autoimmune pancreatitis (AIP), autoimmune-related SC without a pancreatic lesion is very rare. A 79-year-old woman was referred to our ...

Allergic bronchopulmonary aspergillosis (ABPA), which results from hypersensitivity, primarily to Aspergillus, represents a severe complication in patients suffering from asthma or cystic fibrosis (CF). Since early treatment of ABPA is supposed to prevent long-term damages, ABPA has to be diagnosed promptly. However, this diagnosis is not straightforward due to clinical ...

Hypertensive nephrosclerosis alone and in combination with other renal diseases is a leading cause of terminal renal insufficiency. Histologic lesions manifest as benign nephrosclerosis (bN) with arteriolar hyalinosis and later fibrosis. Procoagulant micromilieus have been implicated in fibrosis. Hyalinosis is considered to consist of plasma insudation possibly containing procoagulant factors ...

The cystic lesions of the gastrointestinal (GI) tract demonstrate the various pathologic findings. Some lesions may present a diagnostic challenge because of non-specific imaging features; however, other lesions are easily diagnosed using characteristic radiologic features and anatomic locations. Cystic masses from the GI tract can be divided into several categories: ...

An increase in the frequency of diagnosing non-cystic fibrosis bronchiectasis in children is due to heightened awareness of the disease and the wider availability of high-resolution computed tomography. The most common underlying conditions leading to bronchiectasis include infections, immunodeficiency, aspiration and primary ciliary dyskinesia. Treatment centres on airway clearance with ...

Mediastinal fibrosis is a rare, benign disorder characterised by proliferation of fibrous tissue within the mediastinum. It can present as diffuse mediastinal infiltration or, more frequently, as a localised soft tissue mass, usually in the right paratracheal or subcarinal areas. 18-fluorodeoxyglucose (18-FDG) positron emission tomography (PET) imaging has only been ...

We describe a 45-year-old male patient with recurrent retroperitoneal fibrosis (RPF), in whom a pseudocyst in the peri-aortic fibrotic mantle was diagnosed. Without any intervention other than oral treatment with tamoxifen, the pseudocyst showed significant regression. Although rare, pseudocyst formation may sometimes appear in RPF and may mimic other benign ...

Bronchoalveolar lavage (BAL) has only a limited role in diagnosis of idiopathic pulmonary fibrosis (IPF). A finding of raised neutrophils (>5%) and eosinophils (>2%) is characteristic but not diagnostic of IPF. BAL cell count does not clearly differentiate between fibrotic non-specific interstitial pneumonia and IPF either diagnostically or prognostically. BAL ...
