An adenoid cystic carcinoma (AdCC) of the ceruminous glands is very rare; its diagnosis is most often challenging, and simple biopsies may be misleading. Our paper describes a case of a circumferential mass of the left ear canal that was initially reported as a basal cell carcinoma on biopsies in the clinic and on frozen sections intraoperatively. The final pathology was an AdCC of the ceruminous glands of the external auditory canal. Our case reflects the difficulty in the diagnosis of an AdCC of the ceruminous gland and the importance of keeping broad differential diagnoses in mind when counseling patients with masses in the ear canals until final pathology is obtained...

Although endometriosis is a common condition in women of reproductive age, the incidence of endometrioma in prior surgical incision sites is rare.We present a case of an abdominal wall mass in a female patient with a history of obstetrical surgery. The mass was visualized with ultrasound and computerized tomography, removed by wide excision, and identified via frozen section. This case demonstrates the importance of a thorough surgical and obstetrical history in any woman who presents with an abdominal wall mass...

Articular cartilage injury is a common type of damage observed in clinical practice. A matrix-induced autologous chondrocyte implant was developed to repair articular cartilage as an advancement on the autologous chondrocyte implant procedure. Here, we establish a thin double layer of collagen as a novel and effective bioscaffold for the regeneration of cartilaginous lesions. We created a collagen membrane with double layers using a cover slip, a cover slip, and the collagen was then freeze-dried under vacuum...

AIM: To investigate if there are typical degenerative changes in the ageing sternoclavicular joint (SCJ), potentially accessible for arthroscopic intervention. METHODS: Both SCJs were obtained from 39 human cadavers (mean age: 79 years, range: 59-96, 13 F/26 M). Each frozen specimen was divided frontally with a band saw, so that both SCJs were opened in the same section through the center of the discs. After thawing of the specimens, the condition of the discs was evaluated by probing and visual inspection...

In the last decades, surgical treatment of breast cancer has enormously changed. As a result, nipple-sparing mastectomy (NSM) has evolved as an oncologically safe and cosmetic approach. NSM includes a subareolar frozen section to evaluate malignancy. We determined the accuracy of subareolar frozen section diagnosis, analyzed the discrepancy factor, and estimated the interobserver agreement of frozen section in NSM. A retrospective review of all NSMs at our institution from 2009 to 2015 was performed. Frozen sections were compared to the final diagnoses to analyze the accuracy of subareolar frozen sections...

In the UK, more than 3,200 new cases of cervical cancer are diagnosed each year. Early stage cervical cancer (IA2-IB1) treatment comprises central surgery mainly in the form of radical hysterectomy or fertility sparing surgery including trachelectomy as well as systematic pelvic lymphadenectomy to detect metastases and adjust treatment accordingly. Given the variation in determining the lymph node (LN) status, a major prognosticator, we reviewed the current UK practice of LN assessment in women undergoing surgery for early cervical cancer...

Testicular epidermoid cysts are a rare cause of testicular pathology. No cases of recurrence or metastasis have been reported in the literature. As a result, inguinal partial orchiectomy with frozen section has recently become standard treatment. A 43-year-old male presented with right testicular discomfort and the presence of mass. Right inguinal partial orchiectomy with frozen section was performed, and the right testicle was preserved. The final pathology report confirmed the diagnosis of an epidermoid cyst...

Infiltration by IgG-positive plasma cells is a common finding in tubulointerstitial nephritis. Indeed, it has been thought that CD138-positive mature plasma cells secrete mainly IgG, and the occurrence of tubulointerstitial nephritis with CD138-positive plasma cells secreting IgM has rarely been reported. Routine immunofluorescence of fresh frozen sections is considered the gold standard for detection of immune deposits. However, the immunoenzyme method with formalin-fixed, paraffin-embedded sections is superior for detecting IgM- or IgG-positive cells within the renal interstitium, thus histologic variants may often go undetected...

A ciliated muconodular papillary tumor (CMPT) has been reported to be a low-grade malignant tumor or benign tumor, consisting of ciliated columnar cells and goblet cells with basaloid cell proliferation, occur in the peripheral lung. We present a case of CMPT in this report. A 42-year-old male was referred to our department due to a nodule detected in the peripheral left lower lobe of lung. The nodule was resected via wedge resection based on a suspected diagnosis of carcinoma. Intraoperative analysis of the frozen sections was suggestive of mucinous adenocarcinoma...

BACKGROUND: Insulinomas are the most common pancreatic neuroendocrine neoplasms. In spite of adequate pre-operative localisation, conventional surgical methods rely on intraoperative palpation. Intraoperative ultrasonography (IOUS) is said to aid in accurate localisation, decreases morbidity. Laparoscopic removal of pancreatic endocrine neoplasms is beneficial due to magnification and minimal invasion; however, in the absence of IOUS, error of judgement may lead to conversion to open surgery, thereby relying on 'palpation method' to localise the tumour...

BACKGROUND: The purpose of this study is to determine whether a Stener lesion can be created while testing stability of the ulnar collateral ligament (UCL) of the thumb. Testing was performed in a manner that reproduced clinical examination. METHODS: Six fresh frozen hand and forearm specimens underwent sequential sectioning of the accessory UCL, the proper UCL, and the ulnar sagittal band. Measurements of radial deviation of the metacarpophalangeal (MCP) joint were taken with the thumb in neutral rotation, pronation and supination, both with 0 degrees and with 30 degrees of flexion of the MCP joint...

This study evaluated the effect of chilled followed by frozen storage on lamb quality and safety parameters. Experimental (n=360) M. longissimus lumborum (LL) were randomly sampled from the boning room of a commercial Australian abattoir, at 24 h post-mortem, and assigned to five chilled storage periods (0, 2, 4, 6 and 8 weeks) and six subsequent frozen storage periods (0, 4, 8, 12, 24 and 52 weeks). Upon completion of each storage treatment combination, corresponding LL were sub-sectioned and analysed for colour stability (0, 1, 2 and 3 days), shear force, fluid losses (purge, thaw and cooking losses), intramuscular fat content, sarcomere length, water activity and microbial load (lactic acid bacteria, Enterobacteriaceae sp...

Natriuretic peptides and their specific receptors have been suggested to have regulatory effects on smooth muscle cell (SMC) growth and inflammatory cell reactions. However, the roles of natriuretic peptide receptor A (NPR‑A) and B (NPR‑B) in unstable plaques remain to be studied in detail. Frozen sections from 82 coronary artery segments were used. These segments were obtained at autopsy from 13 patients with acute myocardial infarction (AMI; 7 ruptured and 6 eroded plaques) and from 30 patients with non‑cardiovascular diseases...

Background: When differential diagnosis is difficult in thyroid follicular lesions with overlapping histological features, the immunohistochemical staining can help confirm the diagnosis. We aimed to evaluate the effectiveness of rapid immunohistochemical stains of CD56 and cytokeratin 19 (CK19) on frozen sections of thyroid follicular lesion and explore the possible gains and limitations of the practice. Materials and Methods: Eighty-six nodules of 79 patients whose intraoperative frozen sections were selected as the control group, and 53 nodules of 48 patients whose intraoperative frozen sections were subject to rapid immunohistochemistry were selected as the study group...

Autofluorescent compounds present in intestinal tissue often hinder the ability to utilize multiple, spectrally different, fluorophores. In addition, fixatives and blocking solutions may contribute to background autofluorescence or nonspecific immunofluorescent labeling. During immunofluorescence protocol development, autofluorescent pigments were observed in frozen bovine mid-ileal intestinal tissue sections. Coagulant fixatives, normal serum blocking, histochemical stains Sudan Black B (SBB) and 3,3'-diaminobenzidine (DAB), and spectral separation using imaging software were compared for their ability to reduce autofluorescence, as well as their effect on immunofluorescent labeling...

BACKGROUND: Psoriasis is a common autoimmune disease of unknown etiology. Recently, much attention has been paid to evidence that a local hypercoagulable state is an important contributing factor to the development of inflammatory skin diseases. Thus, the aim of this study was to characterize the local hemostasis in the affected skin of patients with psoriasis. METHODS: Skin biopsies of psoriatic plaques were obtained from 73 consecutive patients (48M, 25F, average age 45 years) with at least a one year history of the disease...

BACKGROUND: Collagen VI is a ubiquitously-expressed macromolecule that forms unique microfibrillar assemblies in the extracellular matrix. Mutations in the COL6A1, COL6A2 and COL6A3 genes result in congenital muscular dystrophy, arguing that collagen is critical for skeletal muscle development and function. Antibodies against collagen VI are important clinical and diagnostic tools in muscular dystrophy. They are used to confirm genetic findings by detecting abnormalities in the distribution, organization and overall levels of collagen VI in cells and tissues isolated from patients...
