ABSTRACT

BACKGROUND: Meningiomas comprise 15%-20% of all primary intracranial tumors. They are generally benign tumors, and most patients are cured after surgery and remain free of recurrence. However, some tumors behave in an aggressive manner, and patients develop local recurrence or metastasis. Overall prognosis is good. PATIENTS AND METHODS: This is an 11-year retrospective study conducted in the Departments of Pathology and Neurosurgery at Sheri-I-Kashmir Institute of Medical Sciences, Kashmir, India. Besides the demographic profile, the parameters analyzed were location of tumor on imaging, histopathological subtype, and grade of tumor according to the 2007 WHO classification and recurrence at follow-up. RESULTS: A total of 254 patients were included in our study, of which 205 (80.7%) were brain meningiomas and 49 (19.3%) were spinal, with an overall female: male ratio of 2:1. Female: male ratio was more in spinal meningiomas, 15.3:1. Most of our patients were in the 4-6th decade of life with a mean age of 48 years (range: 5-73 years). Meningothelial meningioma was the most common histological type. Of ten patients who showed recurrence, seven cases showed only recurrence, but no progression to higher grade and three cases showed recurrence with progression by one WHO-grade. We also noticed that recurrence was higher in Simpson Grades II and III. CONCLUSION: Meningiomas are common in females and most of the meningiomas do well after surgery. The recurrence rate was 3.93% in our study and Simpson grade of tumor excision and histopathological grade contribute significantly to the recurrence of the tumor.

ABSTRACT

Pathological calcification of basal ganglia has been encountered in children since long back and is associated with various disease entities both acute and chronic. Idiopathic hypoparathyroidism is an important cause of basal ganglia calcification and can account for up to 73.8% of cases. The pathogenesis of basal ganglia calcification in hypoparathyroidism is not clear, however, a high calcium-phosphorus product and poor calcium control are believed to be directly related to calcification. Besides, a direct correlation is seen with the duration of hypocalcemia; the critical duration being ≥4 years. In the presented patient, basal ganglia calcification was seen at a very young age of 6 months. To best of our knowledge, this is probably the youngest case of bilateral basal ganglia calcification in idiopathic hypoparathyroidism in literature. This suggests that besides duration of hypocalcemia, certain genetic factors and the intrauterine milieu may have a role in the pathogenesis of basal ganglia calcification.

ABSTRACT

Synovial sarcomas are rare tumors accounting for approximately 5-10% of soft tissue sarcomas. They occur predominantly in the extremities, followed by head and neck. Primary pulmonary sarcomas are very rare and comprise only 0.5% of all primary lung malignancies. The diagnosis is established only after sarcomas like primary lung malignancies, and metastatic sarcomas have been excluded. For synovial sarcomas that arise at unusual locations, a definitive diagnosis is challenging and requires the use of ancillary diagnostic procedures such as immunohistochemistry (IHC) and molecular genetic techniques for confirmation of diagnosis. We report a case of 29-year-old male who had right lower lobe lung mass. He underwent right lower lobectomy. Intraoperative squash smears revealed spindle cell sarcoma. Subsequent histopathology and IHC confirmed the diagnosis as synovial sarcoma. We report this case on account of its rarity and to emphasize the utility of intraoperative squash smears in the diagnosis of such cases, which has been under-utilized in clinical practice.

ABSTRACT

Proteomic analysis using multiplex affinity reagents is perhaps the most reliable strategy to capture differentially expressed proteins that are slightly or immensely modified. In addition to expressional variation, it is comprehensively evident that the immunogenicity of a protein can be a deciding factor for instigating an inflammation afflicted-carcinogenesis. Considering both these factors, a simple and systematic strategy was designed to capture the immunogenic cancer biomarkers from sera of colorectal cancer patients. The affinity reagent, in the form of an antibody repertoire against the secretome of the HT29 cell line was used to grade the sera samples on the basis of the degree of immuno-reactivity and to capture differentially expressed antigens from the patient sera. Following affinity based 2DE-MALDI-TOF; the proteins were identified as (1) soluble vimentin; and (2) TGF-beta-inhibited membrane-associated protein (PP16B), in colon cancer sera and (3) keratin, type II cytoskeletal protein in rectal cancer sera. Pathway reconstruction and protein-protein networking of identified proteins predicted only Vimentin to be physically and genetically engaged in close proximity with the most established colorectal cancer associated tumorigenic pathways. Furthermore, our findings suggest that a possible surface stoichiometric shift in the structure of protein could be due to mutations in the coding sequence of Vimentin that may elicit its enhanced secretion possibly due to protein-hyperphosphorylation. Of the three proteins identified, only Vimentin showed higher expression in sera of colon cancer patients alone. Thus, it could be argued that vimentin might help in predicting individuals at higher risk of developing colon cancers. Our data are therefore suggestive of using vimentin as an antigen for tumor vaccination in an autologous set-up for colon cancers.

ABSTRACT

Distal renal tubular acidosis is a syndrome of abnormal urine acidification and is characterized by hyperchloremic metabolic acidosis, hypokalemia, hypercalciurea, nephrocalcinosis and nephrolithiasis. Despite the presence of persistent hypokalemia, acute muscular paralysis is rarely encountered in males. Here, we will report an eighteen year old male patient who presented with flaccid quadriparesis and was subsequently found to have rhabdomyolysis, severe short stature, skeletal deformities and primary distal renal tubular acidosis.

ABSTRACT

Hashimoto's thyroiditis is associated with an increased risk of developing papillary carcinoma of thyroid. We hereby report a case of Hashimoto's thyroiditis with papillary carcinoma in a 45-year-old ear old female diagnosed on fine needle aspiration cytology (FNAC) which was later confirmed on histopathological examination .Such an occurrence, when both lesions are picked up on FNAC in a patient with no palpable thyroid nodule is rare. The case is presented here for its rarity.

ABSTRACT

Metastatic breast carcinoma is rarely seen in clinical practice. It has been reported that lymphoma-leukemia, melanoma and sarcomas can metastasize to the breast. Bilateral metastases to the breast are rare and commonly have been seen to originate from ovarian carcinoma. Adenocarcinoma of rectum metastasizing to breast is an extremely rare clinico-pathological situation. We report a 28-year-old female who presented with bilateral breast metastasis 9 months after abdomino-perineal resection and total meso-rectal excision for a locally advanced mucinous adenocarcinoma of the rectum. A few case reports of a mucinous adenocarcinoma of rectum presenting with bilateral breast metastasis have been seen in the world literature and we hereby report this case who till now is the youngest patient reported.

ABSTRACT

BACKGROUND: Hepatolithiasis affecting the left hepatobiliary system is common in the Asia Pacific region. This aim of this study was to describe an experience with the diagnosis and treatment of patients with isolated left-sided hepatolithiasis. METHODS: One hundred and ten patients with isolated left-sided hepatolithiasis who underwent a left-sided hepatic resection between January 1999 and February 2010 were included for further analysis. The clinical profile, cholangiograms, operative procedures and early and late results were examined. RESULTS: Analysis of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) findings revealed left hepatic ductal anatomical details in 101 patients. Three types of left hepatic ductal variations were observed (type 1 in 90.1%, type 2 in 5.9% and type 3 in 4.0% patients). Eighty-four (76.4%) patients had the presence of strictures in the left hepatic ductal system and in 26 (23.6%) patients no strictures could be seen. Out of 84 patients with strictures, 78 could be classified (type I in 89.7% and type II in 10.3%). Of the 110 patients, 75 (68.2%) underwent a left lateral sectionectomy, 33 (30%) a left hepatectomy and 2 (1.8%) patients were treated with a left hepatectomy combined with a caudate lobe resection. Of the patients who underwent a left hepatectomy 11.4% developed a bile leak. Eight per cent of patients who underwent a left lateral sectionectomy had infective complications. During a median follow-up period of 63 (range 3-134) months, 2 (2.1%) patients were discovered to have residual stones and five (5.2%) others possessed recurrent stones. CONCLUSIONS: This study highlights the impact of the presence or absence of bile duct stricture on the clinical and histological profile of patients as well as their operative and the post-operative behaviour. It is concluded that hepatic resection is an appropriate treatment modality in localized left-sided hepatolithiasis.
