Background: Despite weak evidence, antibiotic prophylaxis prior to endoscopic ultrasound-guided through-the-needle biopsy (EUS-TTNB) of pancreatic cystic lesions (PCLs) is routinely used in clinical practice. We aim to compare a group of patients treated with antibiotics before EUS-TTNB of PCLs and a group who did not undergo antimicrobial prophylaxis. Methods: Out of 236 patients with pancreatic cystic lesions referred to two high-volume centers between 2016 and 2021, after propensity score matching, two groups were compared: 98 subjects who underwent EUS-TTNB under antibiotic prophylaxis and 49 subjects without prophylaxis. Results: There was no difference in terms of baseline parameters between groups. Final diagnosis was serous cystadenoma in 36.7% of patients in the group not treated with prophylaxis and in 37.7% of patients in the control group, whereas IPMN and mucinous cystadenoma were diagnosed in 3 (6.1%) and 16 (32.6%) versus 6 (6.1%) and 32 (32.6%) patients in the two groups, respectively (p = 0.23). Overall, the adverse event rate was 6.1% in the group not treated with antibiotic prophylaxis and 5.1% in the control group (p = 0.49). Only a single infectious adverse event occurred in each group (p = 0.48). The diagnostic yields were 89.7% and 90.8% in the two groups (p = 0.7), and the diagnostic accuracy rate was 81.6% in both groups (p = 1.0). Conclusions: Prophylactic antibiotics do not seem to influence the risk of infection, and their routine use should be discouraged.

Pancreatic cancer and cholangiocarcinoma are lethal diseases mainly diagnosed at an inoperable stage. As pancreatobiliary surgical specimens are often unavailable for further molecular testing, this review aimed to highlight the diagnostic, prognostic, and therapeutic impact of next-generation sequencing (NGS) performed on distinct small biopsies, including endoscopic ultrasound fine-needle aspirations and biopsies of pancreatic solid and cystic lesions, biliary duct brushings, and also “liquid biopsies” such as the pancreatic juice, bile, and blood. NGS could clarify indeterminate pancreatic lesions or biliary strictures, for instance by identifying TP53 or SMAD4 mutations indicating high-grade dysplasia or cancer. It could also stratify pancreatic cystic lesions, by distinguishing mucinous from non-mucinous cysts and identifying high-risk cysts that should be excised in surgically fit patients, whereas the combination of cytology, elevated cystic CEA levels and NGS could improve the overall diagnostic accuracy. When NGS is performed on the pancreatic juice, it could stratify high-risk patients under surveillance. On the plasma, it could dynamically monitor the disease course and response to therapy. Notably, the circulating tumor DNA (ctDNA) levels have been associated with staging, grading, and survival. Lastly, NGS has shown potential in identifying potentially actionable molecular alterations. In conclusion, NGS applied on small biopsies could carry significant diagnostic, prognostic, and therapeutic value.

Introduction: Some of the ovarian lesions become functional and secrete hormones that bring endometrial changes like hyperplasias and polyps. This study aimed to find endometrial changes associated with different types of cystic lesions of the ovary. Materials and Methods: A histopathological study done from 2010 -2013 on all the total abdominal hysterectomy specimens with bilateral oophorectomy having cyst size more than 3cms, with a detailed clinical history received in the Department of Pathology, Sri Manakula Vinayagar Medical College and Hospital, Pondicherry. A total of 112 cases were collected analyzed and statistically correlated. Results: Out of the 112 cases of cystic lesions of the ovary 67% showed endometrium within normal limits, 33% of cystic lesions of ovary showed polyps, simple hyperplasia without atypia, complex hyperplasia without atypia. Among non-neoplastic lesions, follicular cyst produced the most endometrial changes, followed by benign surface epithelial lesions. Granulosa cell tumor was found to induce polyp as well as simple hyperplasia without atypia. Two out of three malignant lesions showed endometrial changes followed by benign lesions. The majority of the cystic lesions of the ovary encountered are non-neoplastic lesions (59%) and follicular cysts were more common (97%). Endometrial hyperplasia of both simple and complex types without atypia was found with serous cystadenoma. Conclusions:  From the current study it implicates the necessity of assessing cystic lesions of the ovary like a follicular cyst, luteal cyst, granulosa cell tumors as they can become functional leading to endometrial changes that can form a fertile ground for carcinomas.

Pancreatic neuroendocrine tumor (Pan NET) accounts for only 1–2% of pancreatic neoplasms and <1% of tumors present as cystic lesions. A diagnosis of cystic tumor in the pancreas can be very challenging and confusing. Endoscopic ultrasound (USG) and fine needle aspiration (FNA) of these cystic lesions can help the clinician to narrow down the differential diagnosis. A multidisciplinary approach is warranted for a definitive diagnosis and optimal treatment. Here, we present to you a very rare case of Pan NET presenting as a cystic mass. A 65-year-old man was admitted with a history of abdominal pain. Laboratory tests showed increased levels of serum amylase, and other biochemical tests were normal. The patient underwent transabdominal USG and computed tomography (CT). CT showed well-defined cystic lesion in the proximal body of the pancreas. Endoscopic guided FNA (EUS-FNA) using 22 gauges was done. Cytological examination demonstrated clusters and sheets of plasmacytoid cells. EUS core needle biopsy was done which showed loose clusters of cells with fine uniformly distributed chromatin that stained positively for insulinoma associated protein-1 which was suggestive of a Pan NET. The differential diagnosis of cystic lesions in the pancreas is very difficult with conventional radiology such as CT and magnetic resonance imaging. Cytology is helpful for a pre-operative diagnosis of cystic Pan NET. A diagnosis of Pan NET in a pancreatic biopsy or FNA with limited and suboptimal material is often challenging. This unusual case highlights the importance of pre-operative workup of EUS followed by FNAC in cystic pancreatic lesions.

Preterm birth continues to be associated with neurodevelopmental problems including cerebral palsy. Cystic white matter injury is still the major neuropathology underlying cerebral palsy, affecting 1-3% of preterm infants. Although rates have gradually fallen over time, the pathogenesis and evolution of cystic white matter injury are still poorly understood. Hypoxia-ischemia (HI) remains an important contributor yet there is no established treatment to prevent injury. Clinically, serial ultrasound and magnetic resonance imaging studies typically show delayed development of cystic lesions 2 to 4 weeks after birth. This raises the important and unresolved question as to whether this represents slow evolution of injury occurring around the time of birth, or repeated injury over many weeks after birth. There is increasing evidence that tertiary injury after HI can contribute to impairment of white and grey matter maturation. In the present review, we discuss preclinical evidence that severe, cystic white matter injury can evolve for many weeks after acute HI and is associated with microglia activity. This suggests the intriguing hypothesis that the tertiary phase of injury is not as subtle as often thought and that there may be a window of therapeutic opportunity for one to two weeks after hypoxic-ischemic injury to prevent delayed cystic lesions and so further reduce the risk of cerebral palsy after preterm birth.

Mucocele of the paranasal sinuses are benign cystic lesions filled with mucus. They occur in the sphenoid sinus in 1–2% of all paranasal sinuses, most often in the fourth decade of life. Clinical manifestations are non-specific, caused by pressure expansion into anatomical structures immediately adjacent to the sphenoid sinus. They are manifested by headaches, dropped eyelids, impaired movement of the globe, and impaired vision. In the differential dia­gnosis, it is necessary to distinguish them from tumour processes and processes propagating from the intracranium. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) play an important role in the dia­gnosis, the definitive dia­gnosis is determined by perioperative findings and histological examination. Curative surgical options include endoscopic transnasal sphenoidotomy with marsupialization. In this article, we present a case of a patient with a mucocele of the sphenoid sinus, which was the cause of unilateral blindness. Keywords: marsupialization – mucocele – sphenoid sinus – endoscopic transnasal sphenoidotomy

Background: Cystic lesions of the skin and soft tissue are often neglected and thought to be innocuous or harmless. These lesions need to be excised to exclude malignancy. The lesions may present in unusual sites and may also be of infective origin. Thus, there is an urgent need to determine the prevalence and identify the histopathological features of the cystic lesions as the innocuous appearing lesions may actually not be so innocuous. In addition, it is the histopathological features that determine the treatment modality. Aim: To determine the features and prevalence of the types of cysts in skin and soft tissue. Materials and Methods: A retrospective study of the cystic lesions of the skin and soft tissue was conducted. The records from the Department of Pathology, Saveetha Medical College were retrieved and reviewed for patients with cystic lesions of the skin and soft tissue over a one year period extending between January 2019 and December 2019. The records were examined for the following data : age, sex, type of lesion, clinical and histopathological diagnosis. Results: In all 109 cases with skin and soft tissue swellings were analyzed. Among these 53 were males and 56 were more females reported (51 %) of cystic swellings as compared to males (48%). Cystic lesions were most commonly encountered in the age group of 18 to 40 years, which suggests that there may be a role for trauma or occupation related occurrence. A variety of cysts were encountered such as epidermoid cysts (70%), Trichilemmal cyst (7%), and Ganglion (7%).Phaeohyphomycotic cyst, mucous retention cyst, hemangioma and pilomatrixoma. Epidermal cysts were more frequently encountered in males (54%) than females (46%).Most lesions occurred in the back. Conclusion: Epidermal cysts may frequently be associated certain syndromes, hence it is important to evaluate these cysts. In addition phaeohyphomycotic cysts may be mistaken for Ganglion, so histopathological examination is necessary to initiate appropriate therapy.

Highlight :A 26-year-old woman have sterile aerobic and anaerobic bacterial cultures.Pus and splenic tissue examination revealed no bacterial proliferation, while the surgery revealed a splenic abscess.Abstract:We presented a rare case, a 26-year-old woman have sterile aerobic and anaerobic bacterial cultures. Clinical examination of the patient showed a dense cystic mass in the left upper abdomen. Ultrasonography examination suspected a dermoid cyst. However, MRI examination of the abdomen showed turbid cystic lesions. The surgery revealed a splenic abscess, while pus and splenic tissue examination revealed no bacterial proliferation. Based on the literature, the patient had a good prognosis.
