The "floating" posterior inferior glenohumeral ligament (floating PIGHL) is an uncommon cause of posterior shoulder instability. This pathologic lesion, defined as detachment of both the origin of the PIGHL (posterior Bankart lesion) and insertion of the of the PIGHL from its humeral head insertion site, often results in significant and persistent shoulder instability symptoms. An effective sur...

Pulmonary endometriosis is a rarely seen disease of the lung. On computed tomography, a cavitary lesion of 15 × 26 in size was detected in the lung parenchyma of a 38-year-old female patient who was examined due to hemoptysis. The pathologic result of the surgically excised cavitary lesion was reported as pulmonary endometriosis.

An uncommon consequence of intracranial vascular disease is the intramural dissection of blood or "dissecting aneurysm". A 69-year-old man with chronic subarachnoid hemorrhage from a posterior fossa mass lesion and a 30-year-old man with migraine and a brain stem stroke illustrate the diverse etiologic, clinical, radiographic, and pathologic characteristics of this unusual lesion.

Retrorectal cyst-hamartoma, an uncommon lesion, arises from hindgut embryonic remnants and may be associated with sacral anomalies. Such a lesion is presacral, multicystic, and lined with glandular or transitional epithelium. Malignant transformation of these lesions has been reported. We describe the clinical, pathologic, and imaging findings in an infant.

A 34-year-old patient developed an area of thrombus within her placenta. This resulted in severe fetal growth restriction which physicians felt was due to contracting and recovering from the coronavirus disease (COVID-19), during pregnancy. Serial sonograms demonstrated a slowing thrombosis confirmed by pathologic examination placenta after delivery. Since COVID-19 pregnancy are both known hype...

HYPOTHESIS Core-needle biopsy (CNB) and fine-needle aspiration (FNA) play an important role in the initial diagnosis of breast cancer. However, CNB might alter the size of the tumor, which might subsequently change its pathologic stage and thus affect the decision about adjuvant chemotherapy. PATIENTS Between January 2000 and May 2002, we studied 291 patients with invasive carcinoma lesion in...

The risk for lymph node metastasis is low in T1 colorectal cancer when none of the following pathologic findings is present: invasion to a depth of 1000μm or more, positive horizontal or vertical margin, lymphovascular permeation, severe tumor budding, and either a poorly differentiated or a mucinous component [1–3]. To the best of our knowledge, no case of such a low-risk T1 tumor associated w...

objective: we intended to determine causes and histological pattern of hysterectomies in an iranian population. materials and methods: archived reports of pathology department of a university hospital dated march 2005 to march 2009 were retrospectively reviewed. age, chief complaint, type of operation including abdominal, vaginal and subtotal hysterectomy, the indication of the operation and th...

BACKGROUND AND PURPOSE Multiple sclerosis (MS) is the most common inflammatory disease of the central nervous system and manifests both physical and neurocognitive disabilities. Although predominantly a disease of the white matter, MS is also characterized by lesions in the gray matter. Previous pathologic studies have found that cortical and deep gray matter lesions comprised 5% and 4%, respec...
