: Necrobiosis lipoidica (NL) is a granulomatous disease of collagen degeneration classically affecting the lower extremities. Elastophagocytosis is a histological finding, whereby multinucleate macrophages demonstrate phagocytosis of elastic fibers commonly associated with sun-damaged skin. Elastophagocytosis is not typically described in NL. The authors present a patient who presented with reddish-yellow ...

Necrobiosis lipoidica (NL) is a rare chronic granulomatous disease that has historically been associated with diabetes mellitus. Debate exists regarding the etiology and pathogenesis of NL with a widely accepted theory that microangiopathy plays a significant role. NL typically presents clinically as erythematous papules on the front of the lower ...

Benign fibrous histiocytomas (BFHs) and non-ossifying fibromas (NOFs) are benign bone tumors that are clinically different, but histologically similar. Most benign lesions are treated with curettage and grafting; however, some misdiagnosed cases are treated with more aggressive procedures, including arthroplasty. Herein, we present a 21-year-old patient that presented with a ...

The perceived subjective visual vertical (SVV) is an important sign of a vestibular otolith tone imbalance in the roll plane. Previous studies suggested that unilateral pontomedullary brainstem lesions cause ipsiversive roll-tilt of SVV, whereas pontomesencephalic lesions cause contraversive roll-tilts of SVV. However, previous data were of limited quality and lacked ...

Pigmented villonodular synovitis (PVNS) is a rare condition, most commonly involving the knee joint. PVNS is locally aggressive and can invade and destroy surrounding soft tissue and bone, leading to anatomical and functional deterioration of the affected joint. Localized PVNS is an unusual presentation of the disease, generally consisting of ...

Several species of Tenebrionidae are stored-grain pests. Since they belong to a specious family, the systematics of these beetles is still in doubt. In insects, spermatogenesis and the spermatozoa exhibit great diversity, and are therefore commonly used in phylogenetic and taxonomic analyses. During the spermatogenetic process in these organisms, the ...

A 6-year-old male presented with testicular growth and persistent chronic orchiepididymitis with high inflammatory markers (C reactive protein and erythrocyte sedimentation rate). Biopsies of the testes and epididymides showed bilateral epididymal and testicular granulomata, testicular fibrosis and chronic inflammatory infiltration, and the histological diagnosis was granulomatous orchitis. The symptoms receded ...

Abdominal tuberculosis (TB) is the sixth most common location of extrapulmonary TB involvement. Because its symptoms and signs are often nonspecific, laboratory and imaging findings mimic other diseases including carcinoma. Therefore, the diagnosis of abdominal TB is challenging. We herein report a case of 74-year-old woman who presented with abdominal ...

Mucin-producing intraductal papillary neoplasm (adenocarcinoma/adenoma) in the bile duct is becoming recognized as a specific type of neoplasm. Since, it bears a striking similarity to intraductal papillary mucinous neoplasms of the pancreas with regard to its histopathologic features, the term "intraductal papillary mucinous neoplasms of the bile duct" (IPMN-B) is ...

The term "satellite lesions" is used in many conditions in dermatology, generally to describe smaller lesions near the edges of a principal lesion. An online medical dictionary gives the definition "a smaller lesion accompanying a main one and situated nearby," and this can apply both macroscopically and microscopically. The implication ...

The calcifying ghost cell odontogenic cyst (CGCOC) was first described by Gorlin et al. in 1962. Calcifying ghost cell odontogenic cyst is comparatively rare in occurrence, constituting about 0.37% to 2.1% of all odontogenic tumors. The most notable features of this pathologic entity are histopathological features which include a cystic ...

Lesion location might turn out to be an important factor in long-term disability prediction in patients with primary progressive multiple sclerosis (MS). Using a lesion probability mapping approach, researchers have identified brain regions where the presence of MS lesions predicts an early need for bilateral walking support.

The omphalomesenteric duct is an embryologic connection between the digestive tract and yolk sac, which typically involutes by the time of birth. Failure of the obliteration process can result in omphalomesenteric duct remnants. We present two cases of children with such remnants, one with an umbilical polyp requiring traditional excisional ...

IgG4-related systemic disease (IRSD) is a recently described entity with protean manifestations. We describe a patient who developed inflammation and fibrosis in multiple organs over 20 years, sequentially involving his pancreas, bile ducts, gallbladder, submandibular and lacrimal glands, and kidneys. He had an elevated serum IgG4 level. Retrospective analysis of ...

Autoimmune pancreatitis is commonly associated with immunoglobulin (Ig) G4-related sclerosing cholangitis (IgG4-SC). The discrimination between IgG4-SC and pancreatobiliary malignancies or primary sclerosing cholangitis (PSC) is now an important issue. The present study was carried out to examine the usefulness of endoscopic biopsies from Vater's ampulla and the bile duct to ...

Obstruction of the hepatic hilum in patients without prior surgery is generally due to hilar adenocarcinoma (Klatskin tumor). However, not all the hilar strictures are malignant. Although uncommon, benign strictures of the proximal bile duct should be taken into consideration in differential diagnosis of Klatskin tumors, since the incidence could ...

Surgical resection is considered the first-line treatment of intraductal papillary neoplasm of the bile duct (IPNB). Since some patients with IPNB have an unexpectedly superficially-spreading lesion, preoperative cholangioscopic diagnosis is very useful in determining the extent of resection. We report a patient with IPNB in whom preoperative peroral cholangioscopic evaluation ...

Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are ...
