ABSTRACT

Celiac Disease (CeD) is an immune-mediated inflammatory disorder of the small intestine, affecting genetically susceptible individuals when exposed to gluten. Small intestinal biopsy interpretation has been the "gold standard" for celiac disease (CeD) for over 50 years. Despite today's availability of sensitive and specific serological tests, the histopathological features from mucosal biopsy play a key role in diagnosing when CeD is suspected. Such a diagnostic approach requires a multidisciplinary team to optimize both tissue sampling and interpretation via the interaction between the pathologist and the gastroenterologist. Pathologists of the Italian Group of Gastrointestinal Pathology (GIPAD-SIAPEC), together with a member (TR) of the Italian Society of Technicians (AITIC) and an expert gastroenterologist (CC), provide position statements as a practical tool for reading and interpreting the report. Moreover, a position statement was formulated about the recently described condition known as Non-Celiac Gluten Sensitivity (NCGS). Within such a diagnostic setting, both the architectural abnormalities of the duodenal mucosa, namely glandular hyperplasia, and villous atrophy and the number of intraepithelial T-lymphocytes should be well highlighted. Ancillary tests such as anti-CD3 stain are useful for an accurate count of the intraepithelial T lymphocytes when CeD or NCGS is suspected. Moreover, anti-CD3 and anti-CD8 stains are recommended in patients not responding to the gluten-free diet (GFD) to confirm a diagnosis of Refractory Celiac Disease (RCeD). Diagnostic clues about the differential diagnosis of both CeD and RCeD have also been rendered.

ABSTRACT

We report the case of a 70-year-old man with symptoms of urinary obstruction and haematuria, with histological diagnosis of primary signet-ring cell carcinoma of the prostate. Almost 90% of the tumour cells contained characteristic intracytoplasmic vacuoles that positively stained with diastase-digested PAS, Alcian blue and mucicarmine. The positive immunostaining for PSA and PSAP confirmed the prostatic origin of the tumour. Although the patient received hormonal therapy, the disease progressed and the patient died 11 months after surgery.

ABSTRACT

PURPOSE: To investigate the most plausible cause of stillbirth by evaluating clinical records and postmortem examination findings including placental analysis. METHODS: A retrospective cohort study concerning 132 stillbirths from 124 pregnancies occurred in the Mother-Infant Department of the University Hospital of Modena, Italy, from January 2000 to December 2004. Collected data were reviewed and classified according to the Gardosi ReCoDe system. RESULTS: A reasonable cause of fetal death was identified in 99/124 pregnancies (79.84%). No associated relevant factors were disclosed in 25 fetuses (20.16%) classified as unexplained stillbirths. A succeeding scrupulous analysis of the placenta and an accurate clinical record review were useful to detect other conditions in 82 cases, including 5 cases of unexplained stillbirth. The major relevant conditions associated to stillbirths were feto-placental infection especially in the early fetal gestation age, under the 24th week of gestation, and placental insufficiency occurred both in early and late gestation age fetuses and mainly associated with a IUGR (<10th customized percentile). The main frequent secondary conditions were represented by placental anomalies including cluster of avascular villi with stromal fibrosis associated to thrombosis in minor and/or major vessel(s). Through the further analysis of the placenta, we were able to reduce the unexplained stillbirth rate from 20.16 to 15%. CONCLUSION: Accurate fetal autopsy and placental examination related to meticulous clinical collecting data are requisites in the valuation of stillbirth and could play an important role in reduction of unexplained stillbirth rate.

ABSTRACT

We present a case of intraparenchymatous capillary-type hemangioma of the testicle in an adult. The patient was a 37-year-old man who showed a rapidly enlarging and palpable mass in left testicle. Radical orchiectomy was performed, and histological examination revealed an unencapsulated lobulated tumour with wide hemorrhagic portions. To our knowledge, the occurrence of rapid enlargement in a testicular hemangioma has not been previously reported, which might be explained by the development of intra-tumoural haemorrhage.

ABSTRACT

Giant genital haemangiomas are rare occurrences. Once properly diagnosed, they should be managed by surgery with wide and deep margins. We present a clinical case and provide suggestions for diagnosis and treatment of this unusual pathology.

ABSTRACT

Tracheal atresia is an uncommon congenital malformation with a high mortality rate. Clinical symptoms occur suddenly after birth. The diagnosis is suspected in any infant in whom improved ventilation is obtained despite aggressive attempts at resuscitation. We describe a small gestational week 34 male newborn affected by tracheal atresia without esophageal fistula with associated fetal growth restriction, ascites and polyhydramnios. Post mortem examination revealed a diffuse cyanotic status, abdominal ascites and a low birth weight. A 3 cm tract of trachea was documented that distantly ended in a blind pouch and without tracheoesophageal fistulae and enlarged bulky lungs connected to each other by a common thin-walled bronchus. Histological examination showed a normal conformed larynx and scratchily cartilaginous disks in the proximal tract of the short trachea. Vascular space referred to small arteries and veins, thin bands of fibrous tissue and adipose tissue were detected under the blind pouch. Lung distal airspaces were lined by premature cubic epithelium separated by a broad poorly vascularized interstitium. A striking interstitial and alveolar edema was remarkable.
