Bilateral Primary Papillary Serous Carcinoma of the Fallopian Tube.

Primary fallopian tube carcinoma is considered one of the rarest female genital cancers, and its bilateral occurrence is even rarer. Because of the rarity of fallopian tube carcinomas as well as the clinical presentation which simulates an ovarian cancer, a correct preoperative diagnosis of fallopian tube carcinoma is seen only in 4% of cases, and is usually first appreciated by Pathologists. We are reporting our experience of a case of bilateral primary serous carcinoma of the fallopian tube in a 36-year-old female.

Xanthogranulomatous Cholecystitis with Florid Ducts of Luschka: Double Trouble Mimicking Malignancy.

Xanthogranulomatous Cholecystitis (XGC) is an uncommon inflammatory condition of gall bladder, which is often misdiagnosed as malignancy preoperatively, leading to extensive surgical resections which may not be necessary for the patient. Ducts of Luschka are a rare developmental variant of the biliary tree, which are prone to injury and bile leak during cholecystectomy. We report a case of a 52-year-old male patient who was taken up for surgery with a provisional diagnosis of chronic calculous cholecystitis.

Role of fine-needle aspiration cytology in the diagnosis of major salivary gland tumors: A study with histological and clinical correlation.

Introduction: Neoplastic lesions of salivary glands present an interesting subject because of their histologic diversification. Complex features exhibited by them have aroused considerable speculations concerning their histogenesis and continues to hold the interest of clinicians and pathologists. Major salivary glands are superficial and have easy accessibility for fine-needle aspiration cytology (FNAC).

Basal cell adenoma of the parotid gland: Cytological diagnosis of an uncommon tumor.

Basal cell adenoma (BCA) is a rare benign epithelial tumor of the salivary gland, displaying monomorphic basaloid cells without a myxochondroid component, representing 1-3% of all salivary gland neoplasms seen predominantly in women over 50 years of age. It is uncommon in young adults. Cytodiagnosis of basaloid tumors chiefly basal cell adenoma of the salivary gland, is extremely challenging.

Aggressive Digital Papillary Adenocarcinoma-A rare Entity Posing a Diagnostic Challenge.

Aggressive digital papillary adenocarcinoma (ADPCA) is rare tumor of the sweat glands, which is characterised by lesions on the fingers, toes and the digits. The lesion is serious but often overlooked because it is confused clinically with benign and non-tumorous entities. In this paper, we present an interesting case of ADPCA in a 40-year-old lady, suspected clinically as pyogenic granuloma, with the initial excision biopsy indicating a malignant tumor in the sweat gland.

Isolated intracranial rosai-dorfman disease involving the meninges: report of a rare case.

Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease (RDD) is a reactive condition of unknown etiology, characterised by a proliferation of histiocytes exhibiting emperipolesis of lymphocytes and plasma cells. It usually presents as bilateral painless cervical lymphadenopathy. Extranodal RDD without nodal disease is seen in 23% of the cases.

Amelanotic melanoma masquerading as a superficial small round cell tumor: a diagnostic challenge.

Malignant melanoma poses a remarkable capacity for morphological diversity and often presents as a diagnostic challenge due to its wide clinical presentation. We present a case of a 73-year-old lady, with a large superficial ulcerative nodular mass on the flexor aspect of the right upper arm. On fine needle aspiration poorly differentiated round cell tumor was suggested, with histopathology also supporting the same diagnosis.

Soft tissue giant cell tumour of low malignant potential: a rare tumour at a rare site.

"Soft tissue giant cell tumour of low malignant potential" is considered as the soft tissue counterpart of osteoclastoma of the bone. It is a primary soft tissue tumour which is classified under the category of fibrohistiocytic tumours of intermediate malignancy.Seventy percent of the tumours involve the extremities and only about seven percent of them arise in head and neck region.

The cytological grading of malignant neoplasms of the breast and its correlation with the histological grading.

Background And Objectives: Breast carcinoma is one of the leading causes of malignancy in females. The diagnosis of breast carcinoma is often made by fine needle aspiration cytology. Nuclear grading is an important prognostic factor.

Emphysematous pyelonephritis in a diabetic leading to renal destruction: pathological aspects of a rare case.

Emphysematous pyelonephritis is a severe, potentially fatal necrotizing pyelonephritis with a variable clinical presentation, ranging from mild abdominal pain to septic shock. The majority of cases occur in diabetics with poor glycemic control, while a small percentage may be due to urinary tract obstruction. We present a case of a 57 year old male patient, diabetic on treatment, presenting with left flank pain and poor stream of urine since one week.

Isolated primary renal echinococcosis: a rare entity.

Primary renal echinococcosis, a rare entity in diseases involving the kidney, accounts for 2-3 % of all cases. We present a case of 37-year-old female presenting with pain in the right iliac fossa. Radiologically, both ultrasound abdomen and CECT diagnosed as hydatid cyst, mild to moderate hydronephrosis, proximal hydroureterosis, and a possibility of rupturing into the pelvicalyceal system.

Type II First Branchial Cleft Cyst: A Case Report with Review of Literature.

We report a rare case of type II first branchial cleft cyst that presented as an intraparotid cyst. Rarity and varied presentations of the first branchial cleft cysts have led to frequent misdiagnosis. High index of suspicion is required.

Malignant myoepithelioma of the breast: case report with review of literature.

Myoepithelial lesions of the breast are extremely rare and can present with a diverse morphology. We report a case of malignant myoepithelioma characterized by proliferation of atypical oval to polygonal cells expressing typical myoepithelial markers. A 45-year-old lady presented with a mass in the left breast.

Cytomorphology of dedifferentiated liposarcoma of the subcutis of the upper back with axillary lymph node metastasis: a case report.

Background: Liposarcoma in subcutaneous location is rare, and dedifferentiation is extremely rare.

Case: A 65-year-old woman presented with a mass in the upper back of 13 years' duration with a recent history of increase in size. Fine needle aspiration cytology of the mass and axillary lymph nodes showed pleomorphic cells and lipoblasts.

Fine needle aspiration cytology of juvenile hyaline fibromatosis: a case report.

Background: Juvenile hyaline fibromatosis (YHF) is a rare inherited disorder characterized by tumorous growth of hyalinized fibrous tissue. No report on cytomorphology of this condition is available in English on MEDLINE.

Case Report: A 6-year-old girl had multiple nontender nodules on both ear lobes, nose and scalp.

Adult Wilms' tumour: a case report with review of literature.

Background: Wilms' tumor is the commonest primary malignant renal tumor in childhood. Rarely, it may present in the adult age group.

Case Presentation: We report a 48-year-old male presenting with flank pain and haematuria.

Macrofollicular encapsulated papillary thyroid carcinoma--a case report.

Macrofollicular encapsulated papillary thyroid carcinoma (MEPC) is a rare variant of papillary carcinoma of thyroid with a favourable clinical course. It could be mistaken for a follicular neoplasm or a hyperplastic nodule. We report cytological and histopathological features of this rare variant of papillary carcinoma in a 22 year old female with brief review of literature.

Mammary hamartoma--a case report.

Mammary hamartoma is a rare lesion commonly associated with Cowden syndrome. It presents clinically as a fibroadenoma. The nonspecific cytological findings makes the pre-operative diagnosis of this lesion difficult.

Congenital transient myeloproliferative disorder progressing to acute myeloid leukemia in Down's syndrome: a case report.

Chromosomal abnormalities like monosomies and trisomies predispose to various malignancies, hematopoietic or non hematopoietic. Patients with Trisomy 21(Down's syndrome) are prone to acute leukemias during childhood, but congenital leukemia in such children is rare (17%) and should be differentiated from a similar condition -Transient Myeloproliferative Disorder (TMD) which does not necessitate any treatment other than follow up. We report a patient of Down's syndrome with TMD in neonatal period which had spontaneous remission at 3 weeks but later died of acute myeloid leukemia at 6 months.

Squamous metaplasia in a multinodular goiter: a case report.

Squamous epithelium in thyroid is an unusual finding. It is seen in a variety of inflammatory and neoplastic conditions. It's presence has been attributed to metaplastic change of follicular epithelium by some authors and to the persistence of ultimobranchial body by others.
