RESUMO
Background@#Morphological diagnosis of non-Hodgkin lymphoma (NHL) is usually based on lymph node biopsy. Bone marrow biopsy (BMB) is important for staging, and morphology alone can be challenging for subtyping. Immunohistochemistry (IHC) allows a more precise diagnosis and characterization of NHL using monoclonal antibodies. However, there is a need for a minimal panel that can provide maximum information at an affordable cost. @*Methods@#All newly diagnosed cases of B-cell NHL with bone marrow infiltration between 2017 and 2019 were included. BMB was the primary procedure for diagnosing B-cell NHL. Subtyping of lymphomas was performed by immunophenotyping using a panel of monoclonal antibodies on IHC. The primary diagnostic panel of antibodies for B-cell NHL included CD19, CD20, CD79, CD5, CD23, CD10, Kappa, and Lambda. The extended panel of antibodies for further subtyping included CD30, CD45, CD56, Cyclin D1, BCL2, and BCL6. @*Results@#All cases of B-cell NHL were classified into the chronic lymphocytic leukemia (CLL) and non-CLL groups based on morphology and primary IHC panel. In the CLL group, the most significant findings were CD5 expression, CD23 expression, dim CD79 expression, and weak surface immunoglobulin (Ig) positivity. In the non-CLL group, they were CD5 expression, positive or negative CD23 expression, strong CD79 expression, and strong surface Ig expression. An extended panel was used for further subtyping of non-CLL cases, which comprised CD10, Cyclin D1, BCL2, and BCL6. @*Conclusion@#We propose a two-tier approach for immunophenotypic analysis of newly diagnosed B-cell NHL cases with a minimum primary panel including CD5, CD23, CD79, Kappa, and Lambda for differentiation into CLLon-CLL group and Kappa and Lambda for clonality assessment. An extended panel may be used wherever required for further subtyping of non-CLL.
RESUMO
Tumefactive fibroinflammatory lesions [TFLs] are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. TFLs are seen more frequently in males between 10 and 74 years of age. The usual site of involvement is the head and neck region, but rarely the extremities may be involved. Coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosis, sclerosing cholangitis, sclerosing mediastinal fibrosis, and orbital pseudotumors. The etiology of this poorly understood entity remains unknown. Possible suggestions include exaggerated responses or autoimmune reactions to any chronic infection. The clinical and radiological appearance of TFLs is that of malignancy, but histopathology reveals them to be a benign process broadly classified under non-neoplastic, fibroinflammatory proliferations. The treatment strategies for these lesions are not well defined and variable and include steroids, surgery, and radiotherapy either alone or in combination. TFLs, albeit not fatal, have a high recurrence rate; patients should, therefore, be kept on long-term follow-up. We describe a young female patient presenting with a rapidly developing cheek swelling, which was diagnosed histopathologically as a TFLs
RESUMO
Brunner's gland hamartoma is a rare benign tumour of the duodenum. It was first described by Cruveilhier in 1835. Presently around 200 cases have been reported in literature. No sex predilection is seen. Patients usually present in the fifth to sixth decades of life. They may be clinically silent or may present with variable symptoms and occasionally obstructive symptoms and chronic pancreatitis. Endoscopic presentation can be nodular, polypoid or diffuse glandular proliferation with thickening of duodenal wall and hence can be misdiagnosed as malignancy. We describe a case of duodenal tumor reported outside [on biopsy] as well differentiated adenocarcinoma which out as Brunner gland hamartoma upon complete resection. Brunner gland hamartoma may sometimes have a very unusual presentation. Extensive pre-operative evaluation is necessity to avoid radical surgical procedure

Hepatic tuberculosis particularly in the absence of military tuberculosis is rare. It can occur as a primary case or due to reactivation of an old tubercular focus. We report case of a 24 year old married female who died of primary hepatic tuberculosis. She had no evidence of tuberculosis elsewhere. Appropriate treatment initiated early can result in marked recovery whereas failure to recognize this entity can prove to be fatal.

Tuberculosis (TB) of the spleen is an extremely rare clinical entity particularly among immunocompetent persons. We report a case of isolated tuberculous abscess of spleen in a 13- years- old boy. No primary focus of infection was detected in lungs or any other organ. The patient was treated by splenectomy after a therapeutic failure with standard antituberculous medication.

Cysticercosis is a condition that occurs when man is infected with larvae of Taenia solium. Oral cysticercosis is a rare event, and it represents difficulty in clinical diagnosis. A case of oral cysticercosis in 11 year old girl is presented which complained of painless swelling for 6 months. A FNAC was performed which revealed bluish pink fibrillary material and interspersed nuclei and fragments of wall of larvae. Patient was treated with antihelminthic.

Xanthogranulomatous cystitis [XC] is a rare benign disease of unknown etiology. A case of XC in a 30-year-old male is presented due to sparcity of such case report in medical literature. Patient evaluation included clinical, biochemical and radiological studies before treatment. Histological study revealed the rare diagnosis. Patient was asymptomatic at eight weeks follow-up after treatment
