Preferential Solvation Study of Rosuvastatin in the {PEG400 (1) + Water (2)} Cosolvent Mixture and GastroPlus Software-Based In Vivo Predictions

Article claims that rosuvastatin (RST) is a poorly water-soluble drug responsible for limited in vivo dissolution and subsequently low oral systemic absorption (poor bioavailability). The results of inverse Kirkwood–Buff integrals showed the PS of RST by PEG400 as observed in all studied ratios of the binary mixture

Mammary Sarcoma - Not Otherwise Specified: A Case Report

Mammary sarcomas are a heterogeneous group of malignant neoplasms that arise from the mammary stroma. Primary sarcomas of the breast are extremely rare and comprise less than 0.1% of all malignant tumors of the breast. We present the case of a 56-year-old female diagnosed as stromal sarcoma, not otherwise specified - a very rare entity

Cytological diagnosis of multiple myeloma presenting as a jaw swelling

Multiple myeloma is a systemic B-cell lymphoproliferative disease with varied manifestations. Its diagnosis can therefore pose difficulties for both the clinicians and pathologists. Jaw lesions, though not uncommon, rarely present as the first sign in multiple myeloma. We present here the case of a 45 year-old female who presented with a swelling of the jaw and on subsequent work-up, was diagnosed with multiple myeloma. Recent research regarding this disease has also been highlighted

Diagnosis of Rosai-Dorfman Disease in Elderly Female on Fine Needle Aspiration Cytology: A Case Report

Rosai-Dorfman disease (RDD) is a rare benign disorder of histiocytic proliferation that usually presents with bilateral cervical lymphadenopathy in children. We describe the case of a 50-year-old lady suffering from this disease who presented with generalized lymphadenopathy and a left sided chest wall lump. Fine needle aspiration cytology (FNAC) from all the lesions showed abundant benign histiocytes with lymphophagocytosis which was compatible with the diagnosis of RDD. This case is being reported for its rarity in presentation in an elderly female with both generalized nodal as well as extranodal manifestations

Atypical Proliferating Clear Cell Adenofibroma of the Ovary: A Case Report

Clear cell adenofibromas of borderline malignancy are extremely rare tumors of theovaries. They may be associated with ovarian clear cell adenocarcinomas which typically present as large adnexal masses and are generally considered highly malignant. We describe the case of a postmenopausal female with an ovarian mass diagnosed as atypical (borderline) proliferating clear cell adenofibroma. The patient is alive and wellwithout signs of recurrence three years after surgery

Metastasis to left scapula with unknown primary: Approach to pathological diagnosis

Bony metastasis is a frequent occurrence in malignancy. However, the clinical presentation and pathological findings may sometimes be more in favor of a primary bone lesion. In such cases, immunochemistry has a very important role to play in reaching a final diagnosis. We present the case of a 35 year male patient who was investigated for a lytic lesion in the left scapula and was finally diagnosed with metastatic adenocarcinoma with the help of immunostaining

A comparison of cytological and histopathological findings and role of immunostains in the diagnosis of soft tissue tumors

Background: Fine needle aspiration cytology (FNAC) has been employed as a useful technique for the initial diagnosis of soft tissue tumors (STT) as well for the identification of recurrent and metastatic cases. Aim: We conducted this study on soft tissue tumors to find the efficacy of FNAC and to finalize the histological diagnosis with immunostains. Materials and Methods: The present study was conducted on 126 patients of soft tissue tumors. FNAC and histopathology was performed in all the cases. Results: Hundred and five cases (83.3%) were diagnosed as benign and 21 cases (16.7%) as malignant. On FNAC, tumors were divided into six cytomorphological categories i.e. lipomatous, spindle cell, round cell, myxoid, pleomorphic and vascular tumors. Seventeen cases were inconclusive on cytology. In five cases, the type of malignancy was changed on histological examination. There were three false positive and two false negative cases giving a positive predictive value of 97.2 % in terms of malignancy, a sensitivity of 98.1% and a specificity of 96.7%. Conclusions: FNAC has a definite role in forming the initial diagnosis of STT, while histopathology with the aid of immunomarkers provides the final diagnosis
