Biphasic synovial sarcoma with epithelial predominance reminiscent of adenocarcinoma: a diagnostic challenge.

Synovial sarcoma (SS) is a rare tumour of unknown origin with peak incidence between 10 and 35 years. Although it arises in juxta-articular location, SS is a misnomer and has no true relationship with synovium. In this case report, we present an elderly female patient with a long-standing history of thigh mass which was initially misdiagnosed as metastatic adenocarcinoma deposits on fine needle aspiration cytology, and again misdiagnosed as malignant adnexal skin tumour on core needle biopsy and referred for further management.

Acquired Angioedema: A Rare Manifestation of Angioimmunoblastic T Cell Lymphoma.

The clinical presentation except age of onset is similar in different types of angioedema. A lymphoproliferative disorder like angioimmunoblastic T cell lymphoma (AITL) rarely presents with symptoms of angioedema. We present extremely rare case of elderly male with recurrent tongue swelling, pruritus with normal levels of complements and C1 esterase inhibitor protein featuring as acquired angioedema, a rare manifestation of AITL.

Pap Smears in Endometrial Adenocarcinoma: Does It Have a Role?

Background: Historically the conventional Pap smear has been an effective screening tool for Carcinoma cervix. However the reporting of benign and malignant endometrial cells on Pap smear has remained controversial. There are very few studies addressing the utility of Pap smears in diagnosing endometrial carcinomas.

Spontaneous Partial Vanishing Cytomegalovirus Pseudotumour of Colon in an Immunocompetent Patient.

Cytomegalovirus (CMV) pseudotumour of the gastrointestinal tract, is a rare benign entity which is treated with antiviral medications and known to resolve spontaneously in a few cases. This is a case report of a 58-year-old man who presented with right lower quadrant abdominal pain. Contrast enhanced computerized tomography of abdomen and pelvis showed apple core lesion involving proximal transverse colon, ceacum, ascending colon, ileoceacal valve and terminal ileum.

Aggressive nodular fascitis of the mandible in a child: a rare case report.

Nodular fascitis is a benign, reactive, fiboproliferative lesion that is thought to represent an over exuberant reaction to injury or inflammation. Its histological picture is very similar to fibro sarcoma. An accurate diagnosis is imperative to avoid unnecessary aggressive treatment.

Meckel gruber syndrome: report of two cases with review of literature.

Meckel Gruber syndrome (MKS) is a lethal, autosomal, recessive, multisystemic disorder, associated with mutations affecting ciliogenesis. Since the time it was first reported; only 200 cases have been reported. From January 2004 to December 2010, we evaluated 268 fetal autopsies in our institute, in the Department of Pathology; two of these fetuses were diagnosed as MKS.

Osteonevus of Nanta Presenting as Nodule over Left Eyebrow.

Osteonevus of Nanta is a rare histopathological finding in which there is an ectopic bone formation in intradermal nevus. Very few cases have been reported so far in the literature. We present a case of osteonevus of Nanta, which occurred as a nodule over the left eyebrow in a 52-year-old female patient.

Chiari III Malformation: a rare case with review of literature.

The Chiari Malformation is a neural tube defect involving the posterior cranial fossa and the hind brain, characterized by herniation of the posterior fossa contents below the level of the foramen magnum. Four types were described by Hans Chiari in the late 19th century. Of these, Type III is exceedingly rare.

Type I punctate palmoplantar keratoderma (Buschke-Fisher-Brauer disease) in a family--a report of two cases.

Background: Inherited palmoplantar keratoderma are a rare group of disorder affecting the palm and sole characterised by hyperkeratosis resulting in severe disability and deformities.

Objective: To report a rare case of punctate palmoplantar keratoderma.

Method: A case attending our OPD is reported.

Transfusion induced Graft versus host disease - Case report in a 2 year child.

Graft-versus-host disease (GVHD) is a rare, almost always fatal complication of a blood transfusion. It occurs much more commonly after bone marrow transplantation, a setting in which it is less severe-mortality rate of 20-25% following transplantation versus 80-90% when associated with a transfusion. Transfusion associated GVHD occurs in two settings: when the recipient is immunodeficient; and when there is a specific type of partial HLA matching between the donor and recipient.

Iniencephaly clausus: A case report with review of literature.

Iniencephaly is a rare neural tube defect characterized by extreme retroflexion of the head with the absence of neck due to spinal deformities. The important features that help us to diagnose a case of iniencephaly are occipital bone deficit leading to enlarged foramen magnum, fusion of malformed cervical and thoracic vertebrae, and upward turned face with chin continuous with chest because of the absence of neck. The differential diagnoses include anencephaly with spinal retroflexion, Klippel-Fiel syndrome, nuchal tumors such as teratoma, goiter, and lymphangioma and Jarcho-Levin syndrome.

Nodular hidradenoma of male breast: Cytohistological correlation.

Nodular hidradenoma is an established entity as a skin adnexal tumor arising from eccrine sweat glands. A skin adnexal tumor located in the breast is unusual and is one of the differential diagnoses for subareolar breast nodules. With the exception of gynecomastia, other lesions of the male breast are not very common.

Multiple cutaneous malignancies in a patient of xeroderma pigmentosum.

Xeroderma pigmentosum is a genodermatosis characterized by photosensitivity and the development of cutaneous and internal malignancies at an early age. The basic defect underlying the clinical manifestations is a nucleotide excision repair defect, leading to defective repair of DNA damaged by ultraviolet radiation. These patients exhibit enhanced sensitivity to ionizing radiation.

Primary renal synovial sarcoma.

Primary synovial sarcoma (SS) of kidney is very rare and difficult to diagnose. Here, we present a case of a 21-year-old female clinically diagnosed as renal cell carcinoma. Right nephrectomy specimen showed a cystic tumor in the upper pole of kidney with areas of hemorrhage and solid growth.

Lipoma arborescens of knee joint: role of imaging.

A 23 year old Asian female presented with swelling of right knee joint for 5 years with history of exacerbations and remissions of symptoms. She was initially diagnosed as a case of suprapatellar bursitis based on clinical and X-ray findings. Further evaluation with higher imaging modalities was pathognomonic of lipoma arborescens.

Scar endometriosis.

Endometriosis is the presence of functioning endometrium outside the uterus. Endometriosis rarely occurs in the abdominal wall. Majority of abdominal wall endometriosis occur in or adjacent to surgical scars, following caesarean section or hysterectomy.

Idiopathic infantile arterial calcification with thrombotic microangiopathy--a unique case.

Idiopathic Infantile Arterial Calcification (IIAC) is a rare syndrome of unknown cause characterized by disruption and calcification of the internal elastic laminae of fetal arteries with calcium deposits leading to fibrosis and occlusion of the arteries. The diagnosis is often made at post-mortem examination. However, in a few cases it has been detected prenatally as in this case.

Pseudoepitheliomatous, keratotic, and micaceous balanitis presenting as cutaneous horn in an adult male.

Pseudoepitheliomatous, keratotic, and micaceous balanitis is an extremely rare condition occurring over the glans in elderly characterized by silvery white plaque with mica-like crust, which can undergo malignant transformation. Herein we present a case of pseudoepitheliomatous, keratotic, and micaceous balanitis occurring in an adult male presenting as a cutaneous horn.

Lingual ulceration in disseminated histoplasmosis.

Histoplasmosis is a rare systemic fungal infection commonly presenting as mucosal ulceration of the oral cavity. It has been increasingly reported in India as disseminated disease with lesions in the oral cavity as a consequence of rapid spread of HIV infection. The authors report a case of disseminated histoplasmosis with oral manifestation in a 40-year-old male patient.
