Spindle cell variant of papillary thyroid carcinoma: A diagnostic challenge - A rare case report with brief review of literature.

OBJECTIVE: Primary Spindle cell tumors of the thyroid are very rare and comprise a myriad of differential diagnoses ranging from reactive proliferations to neoplastic processes. Differentiation amongst these rare entities is of utmost importance as it defines the prognosis and also guides future therapy. CASE REPORT: Hereby, we present a rare case of spindle cell variant of papillary thyroid carcinoma in a sixty-four-year-old female which posed a diagnostic challenge on histology. Microscopy showed a well-circumscribed spindle cell lesion with areas of infiltration and entrapment of colloid-filled thyroid follicles. There were no characteristic features of papillary carcinoma. A panel of immunohistochemistry markers was advised which clinched the diagnosis as the spindle tumor cells were positive for thyroid papillary carcinoma markers. Although papillary carcinoma usually has an indolent course, however interestingly this patient presented with lymph node metastasis one month after surgery which cytologically showed features of malignant spindle cell neoplasm. CONCLUSION: Through this case report we wish to highlight the cytological, histopathological as well as immunohistochemical features of this rare variant of papillary carcinoma.

Cytological Diagnosis of Pilomatrixoma and its Diagnostic Pitfalls.

Background: Pilomatrixoma (PMX) is a relatively uncommon benign cutaneous neoplasm arising from skin adnexa. It presents as a subcutaneous asymptomatic nodule mostly in the head and neck region and is frequently misdiagnosed by the clinicians. Although easily diagnosed on histopathology, the cytologic features of PMX are less distinctive, depending on the stage and evolution of disease and may mimic other benign or even malignant lesions. Aim: To study the cyto-morphological features of this uncommon neoplasm and identify its potential diagnostic pitfalls on fine needle aspiration cytology (FNAC). Material and Methods: Archival records of histopathologically diagnosed Pilomatrixoma were analyzed during study period of 2.5 years. Clinical diagnosis, preoperative FNA characteristics, and histopathological details were studied in each case. Cytologic pitfalls resulting in misdiagnosis of PMX cases on FNAC were evaluated in discordant cases. Results: The series showed male preponderance, with head and neck being the commonest site. Out of 21 histopathologically proven cases of PMX, cytological correlation was available in 18 cases. A correct cytologic diagnosis of PMX/adnexal tumor was rendered in 13 cases. Erroneous diagnosis was given in 5 cases mainly because of the predominance of one component over the other or non-representative-aspirated material. Conclusion: The present study highlights the importance of careful screening of FNAC smears keeping in mind the variability in the relevant cytologic features of PMX and creates awareness about the lesions that can mimic Pilomatrixoma resulting in diagnostic dilemma.

A histopathological and immunohistochemistry analysis of endometrial lesions among women presenting with abnormal uterine bleeding.

Objectives: We aimed to histopathologically evaluate the morphological spectrum, apoptotic index (AI), and mitotic index (MI) of endometrial lesions in patients presenting with abnormal uterine bleeding (AUB). Methods: A cross-sectional study was done over a period of 18 months where a total of 60 newly diagnosed cases of perimenopausal women presenting with AUB were included. All H and E stained pathology slides from the specimens were reviewed for initial histopathological evaluation and diagnosis. Immunohistochemistry for Bcl-2 and Bax was done. The study subjects were divided into two groups: Group 1 included 30 cases of histologically proven proliferative endometrium (PE) and endometrial polyps and Group 2 included 30 cases of hyperplasia, endometrial epithelial neoplasia (EIN)/or carcinoma. For all cases, AI and MI were calculated and compared among the two groups. Statistical Analysis: Quantitative variables were compared using the Independent t-test/Mann-Whitney test between the two groups and Kruskal-Wallis test for comparison between more than two groups. Qualitative variables were correlated using the Chi-square test. P < 0.05 was considered statistically significant. Results: In our study of 60 patients of AUB, the mean age was 45.87 years with a parity of 2 or more in most of the patients. Most of the patients in our study had heavy menstrual bleeding (66.67%) with associated complaints of weakness, pallor, and low backache. Out of 60 patients of AUB, Endometrial carcinoma was diagnosed in 13 (21.67%) patients, with the most common histopathological type being Endometrioid carcinoma. There was a significant difference in the AI, MI, and the ratio of AI/MI among various histopathological diagnoses. AI was highest for Endometrial carcinoma and lowest for hyperplasia and polyps. MI was also highest for Endometrial carcinoma and lowest for hyperplasia and polyps. However, the ratio was incongruent as it was highest for hyperplasia without atypia and lowest for PE with endometrial carcinoma being midway. The Bcl-2 expression of relatively benign conditions (Group 1) was significantly higher than Group 2 (Endometrial epithelial neoplasia/carcinoma). Bax intensity showed an almost inverse pattern, being highest in endometrial carcinoma and lower in hyperplasia and polyps with the lowest expression in PE. Even the Bcl-2:Bax ratio was also highest for PE and lowest for endometrial carcinoma with others falling in between them. Conclusion: It can be concluded that the combination of the proliferative and apoptotic markers and the ratio will help as a tool in aiding the diagnosis of endometrial lesions for patients presenting with AUB.

Critical Analysis of Laboratory Requisition Forms Received in a Cytopathology Laboratory of a Tertiary Care Centre: An Audit and Review of Literature.

Background: A laboratory requisition form (LRF) is the main communication link between the laboratories and the clinicians. In a cytopathology laboratory, incomplete forms with inadequate information significantly impact the quality of the results and waste precious time of the lab. Aims: The aim of this study was to audit the LRFs for adequacy of demographic and clinical data and to analyze the reasons for the same. Settings and Design: A retrospective study was conducted in the cytopathology laboratory of a tertiary care center. Materials and Methods: All the original LRFs received for Pap smears and FNACs of 1-month duration were retrieved. The forms were scrutinized for the presence of specific parameters which were classified as patient information, clinician information and clinical information. In addition to the completeness of the form, clarity of the data was also noted. Statistical Analysis: The data were entered on excel worksheets and percentage of Pap smear and FNAC forms lacking information of various parameters was calculated. Results: A total of 431 LRFs were received in the month of January 2020. These included 274 Pap smear LRFs and 157 FNAC LRFs. Patient information was mentioned in predominantly all the forms, however, clinician and clinical information, which is indispensible for reporting, was missing in a significant proportion of the Pap smear and fine needle aspiration cytology (FNAC) forms. Conclusions: Receiving inadequately filled LRFs has been an age-old problem in all medical laboratories. Audit of inadequacy of LRFs helped in assessing the prevailing practices in the hospital and gave an insight into the quality of information available to the cytologists for reporting. Many clinicians withhold information out of ignorance about its importance or due to lack of time to fill up the details on the LRF. Also, filling out a LRF is a task usually delegated to the junior doctor in the OPD and the significance of filling the LRF correctly and comprehensively is often not emphasized upon adequately by the senior clinicians. This audit helped us taking preventive action by giving feedback to the clinicians and emphasizing to them the importance of clinical data on the LRF and in improvising the LRF using a more objective and user-friendly format.

Peripheral giant cell granuloma of maxilla.

It is often documented that chronic irritation could be an etiology of oral cancer; yet out of negligence little heed is paid to any sort of discomfort until it grows to a sizable mass where it is difficult to go unnoticed. Intraorally, the source of irritation could vary from a jagged tooth edge to a chronic cheek bite. Furthermore, the removable prosthesis and orthodontic appliances can lead to alteration of the oral mucosal tissue. This case report represents one such sequelae of an ill-fitting dental prosthesis. Surprisingly and unfortunately, the broken denture was still in use by the patient until the damage caused by it could no further be ignored, it is then that the patient sought medical help. A histopathological diagnosis of reparative giant cell granuloma was made, and the patient was treated by successful excision of the same.

Importance of eosinophilic structures and its correlation with acid fast bacilli in fine needle aspiration smears of tubercular lymphadenitis.

BACKGROUND: The hallmark of tuberculosis in cytological smears is the presence of epithelioid cell granulomas, necrosis and AFB. In cases, where AFB not detected, diagnosis of tuberculosis can be made by ancillary tests like PCR which requires infrastructure besides being expensive. In India, where majority of population is rural-based there is an imminent need of some morphological change in cytological smears which can point towards diagnosis of tuberculosis in absence of AFB. This study was done to assess the importance of eosinophilic structures (ES) and its correlation with presence of AFB. MATERIAL & METHODS: This was a retrospective study over a period of one year. Lymph node aspirates reported as granulomatous lymphadenitis, tubercular lesion or suppurative lesion were included. All smears for each case, stained with May Grunwald Giemsa (MGG), Hematoxylin and Eosin (H&E) and ZN stain were retrieved and rescreened for the presence of eosinophilic structure, necrosis, granulomas and AFB. RESULTS: Our study included 256 cases. Most common age group was 21-30 years with female predominance. Cervical lymph nodes were most commonly involved. In relation to ES and AFB four cytological pictures were seen i.e ES + AFB+ (44.54%) ES + AFB- (5.46%) ES- AFB+ (14.45%) ES - AFB- (35.55%). Chi square test showed a high significant statistical association between ES and AFB(p = 0.00001). CONCLUSION: In developing countries with very high TB prevalence like India, where new diagnostic modalities are unaffordable by rural population, presence of ES should be included as a morphological parameter in routine cytology reporting of tubercular lesions.

Xanthogranulomatous cholecystitis mimicking advanced gallbladder carcinoma - Analysis of 8 cases.

BACKGROUND/AIM: Xanthogranulomatous cholecystitis (XGC) is a rare destructive inflammatory disease of the gallbladder. It is frequently misdiagnosed as gallbladder carcinoma (GBC) as it mimics latter with regard to clinical manifestations, imaging and intraoperative findings, often leading to extended surgical resection in these patients. The aim of this study was to evaluate the diagnostic dilemma of XGC cases clinico-radiologically diagnosed with GBC. MATERIALS AND METHODS: From January 2017 to June 2019, a total of eight cases histopathologically diagnosed as XGC, were misdiagnosed with GBC based on preoperative and intra-operative findings. The clinical characteristics, imaging, intra-operative findings, and surgical data of these patients were collected and analyzed. RESULTS: A total of 2154 cholecystectomy specimens were received in the histopathology section during the study period. Sixty-nine cases (3.2%) were histologically diagnosed as XGC, of which 8 cases (11.6%) were preoperatively diagnosed with GBC. These cases were predominantly seen in males in the age range of 24-62 years. The most common clinical presentation was chronic cholecystitis. Gallstones were present in all the 8 cases. Six cases presented with heterogeneous enhancement within thickened gallbladder walls on imaging. Intraoperatively, adhesions to adjacent organs were observed in seven cases. All these eight cases misdiagnosed with GBC underwent aggressive surgical treatment following which histopathology ultimately revealed XGC. CONCLUSION: Neither clinical manifestations nor laboratory tests/radiological methods can provide an effective means of differentiating between XGC and GBC. Preoperative diagnosis is difficult, and histopathology remains the gold standard to differentiate the two entities.

Recently Described Entity of Intracholecystic Papillary Neoplasm of Gallbladder with Coexisting Xanthogranulomatous Cholecystitis: an Unusual Association.

Intracholecystic papillary neoplasm (ICPN) of the gallbladder is a relatively new concept and is suspected to share clinicopathologic features with intraductal papillary mucinous neoplasm (IPMN) of the pancreas and intraductal papillary neoplasm of the bile duct (IPNB). The literature on the clinicopathologic characteristics of preinvasive intraepithelial neoplasms of the gall bladder is fairly limited, partly owing to variability in its definition and terminology. We report an extremely rare case of coexistent xanthogranulomatous inflammation and intracholecystic tubulo-papillary neoplasm with low-grade dysplasia in a 48-year-old male patient. Although there are many case reports of simultaneous carcinoma gallbladder with xanthogranulomatous cholecystitis (XGC), however, the association of ICPN with XGC has not been previously described. To the best of our knowledge, this is the first case report of ICPN of gallbladder coexisting with xanthogranulomatous cholecystitis.

Toward early diagnosis of oral cancer: Diagnostic utility of cytomorphological features, a pilot study.

INTRODUCTION: Early detection of oral cancer is one of the most efficient ways to reduce the high mortality from this disease because of the ready accessibility of the oral cavity. We need to devise urgent diagnostic tools to detect early oral premalignant and malignant lesions. AIM: The aim of the present study was to grade the oral lesions in an attempt toward developing a novel cytological grading system. Further, morphometric analysis of cellular parameters was also performed to compare their significance in differentiating benign from malignant lesions. MATERIALS AND METHODS: The present study was conducted at a tertiary care hospital catering to the low socioeconomic population. Patients presenting in the various Out Patient Departments with suspicious oral lesions were evaluated by cytology in the Department of Pathology. RESULTS: A total of 72 patients were evaluated with a mean age of 43.54 ± 10.35 years. The involvement of the buccal mucosa was the most common site of oral lesions. Cytologically, the lesions were graded according to the oral/oro-pharyngeal cytology grading system into grades A to F. Cyto-morphometric analysis showed an increasing trend in mean nuclear diameter from benign to malignant cases while the mean cytoplasmic diameter decreased, value of P < 0.05 was observed indicating a statistically significant difference between the two groups. CONCLUSIONS: Cytological features of pleomorphism are a unique feature in oral carcinoma reflecting intracellular alterations in cells. Grading of lesions according to cytological characteristics can be helpful in standardizing the reporting of the oral lesion. However, our study was restricted by limited data; we emphasize more extensive studies to assess the usefulness and applicability of such a grading system. We also conclude that the use of cytomorphometry can improve the diagnostic reliability of exfoliative cytology.

Pancreatic and Gastric Heterotopia in the Gallbladder: A Rare Incidental Finding.

Heterotopic or ectopic tissue is a congenital anomaly, which is defined as the presence of the tissue outside its normal location, without neural, vascular, or anatomic connection with the main body of an organ in which it normally exists. This tissue is usually discovered incidentally and may be asymptomatic or may present with nonspecific gastrointestinal (GI) symptoms. Pancreatic and gastric heterotopia are the two predominantly occurring heterotopic tissues in the GI tract.[12] The prevalence of ectopic pancreatic tissue in the GI tract ranges from 0.6% to 13.7% of autopsy series and it can be present anywhere in the GI tract with the most common localizations being stomach (27.5%), duodenum (25.5%), colon (15.9%), esophagus, and Meckel's diverticulum.[345] It is a rare finding in the gallbladder and its prevalence has not been ascertained due to lack of large-scale studies and systematic review of literature. Similarly, heterotopic gastric tissue is common throughout the GI tract from the tongue to the rectum,[67] but it is extremely rare in the gallbladder with only around 34 cases reported in literature so far, while other cases of different types of heterotopic tissues in the gallbladder such as liver tissue and others such as adrenal and thyroid tissues have been described.[8] The most common presentation of ectopic tissue in the gallbladder is colicky pain in the epigastrium or right upper quadrant sometimes associated with nausea and vomiting. Here, we are presenting two incidentally detected cases, each of gastric and pancreatic heterotopias in the gallbladder.

Video projected practical examination as an introduction to formative assessment tool for undergraduate examination in pathology.

BACKGROUND: Assessment of the medical students includes theory as well as practical assessment. Traditional practical examination in pathology which includes viva and spots is now increasingly being questioned because of their inherent lack of validity and reliability, time consumption, and human resource requirement. Therefore, a need was felt for another form of practical examination which can be used as formative assessment, and if found feasible, can be employed in summative assessment too. AIM: The aim of the study was to develop and implement a new method of video projected practical examination (VPPE) as a formative assessment tool for MBBS second professional students so as to improve their learning and academic performance in practical pathology and also to obtain students' perception regarding the effectiveness of VPPE. METHODOLOGY: The study was carried out with the MBBS second professional students before their end-of-semester examination in the Department of Pathology. In this new method, slide video projection was used as a formative assessment tool during practical examination. Students were randomly divided into two groups. Group I was subjected to VPPE, while simultaneously conventional practical examination was held for Group II. Assessment results of VPPE were compared with conventional practical examination. Faculty and students feedback was also taken at the end of the examination. RESULTS: Mean marks of the students who undertook VPPE was higher than those who gave conventional practical examination. Majority (95.3%) of the students agreed that VPPE is better than conventional practical examination. Most of the faculty members also felt that it is a more valid and reliable assessment tool. CONCLUSIONS: Introducing VPPE as a formative assessment tool in practical pathology enhanced their learning and academic performance. Opinion of examiners and students also showed that VPPE has several advantages over conventional practical examination.

Synchronous benign Brenner's tumor of ovary with leiomyoma and endometrial adenocarcinoma in a postmenopausal female.

Brenner tumors of ovary are usually an incidental finding. It is an uncommon tumor which is seen affecting women of fifth to sixth decade. It is classified under transitional cell tumors of ovary, which includes benign, borderline, and malignant Brenner tumors and transitional cell carcinoma. These tumors have been associated with synchronous and metachronous neoplasia, most commonly other ovarian epithelial tumors such as mucinous cystadenoma. Occasionally, these tumors may be associated with endometrial hyperplasia or carcinomas which are due to hormones elaborated by the stromal component of Brenner tumor. The hormone produced is estrogen and less commonly androgens, which alters the estrogen and progesterone levels, causing hyperstimulation of endometrium. We present a case of 50-year-old postmenopausal women who presented with coexisting incidental Brenner tumor with leiomyoma and Endometrial adenocarcinoma. Only few authors have reported similar tumor occurrence in the past.

Retained Fetal Bones: An Unusual Cause of Granulomatous Reaction on Papanicolaou Smear.

Granulomas are a rare finding on Papanicolaou (Pap) smear which if encountered are usually attributed to tuberculosis, especially in an endemic country like India. Here, we report an interesting case of a 40-year-old female presenting with blood-stained discharge and chronic pelvic pain for 8 years. She was advised Pap smear which showed granulomatous inflammation suggestive of tuberculosis. The patient was worked up for tuberculosis which was noncontributory. Dilatation and curettage was done which revealed multiple small bones and bony chips in the endometrial cavity. Following the removal of bones, the patient showed considerable symptomatic improvement. Repeat Pap smear did not reveal any evidence of granuloma. Even after extensive search of literature, we did not come across any such case report in which intrauterine retention of fetal bones evoked a granulomatous response in cervical smears though the presence of uterine granulomas in response to foreign body has been well documented.

Poorly differentiated carcinoma of thyroid: Case report of an uncommon entity.

Malignant thyroid tumors of follicular origin comprise a spectrum, with the indolent well-differentiated thyroid carcinoma (WDTC) at one end and lethal anaplastic thyroid carcinoma (ATC) at the other. Poorly differentiated thyroid carcinoma (PDTC) lies intermediately between WDTC and ATC in terms of morphology and prognostic standpoint. This thyroglobulin producing neoplasm accounts for 4-7% of all thyroid malignancies. PDTC has been controversial due to lack of defined diagnostic criteria. We hereby report a case of PDTC in a 42-year-old female presenting with neck swelling, pain, and dysphagia for 10 months. She was diagnosed as colloid goiter on fine-needle aspiration cytology. On imaging, a large complex thyroid with central neck nodes was seen. Total thyroidectomy and central neck node dissection were done. Based on the morphology, immunostaining, and the diagnostic criteria, a diagnosis of PDTC was made. PDTC is a diagnostic challenge due to its rarity and previous equivocal diagnostic criteria.

Diagnostic challenges of tubercular lesions of breast.

INTRODUCTION: Tuberculosis (TB) in the developing countries presents with both pulmonary and extrapulmonary manifestations. Breast TB, however, remains a rare presentation. Its importance lies in the fact that it may mimic malignancy or present as inflammatory lump/abscess. AIMS AND OBJECTIVE: The aim of the present study is to highlight the importance of breast TB and its diagnostic challenges. MATERIALS AND METHODS: It was a retrospective study conducted at a tertiary care hospital, over 2 years between 2013 and 2015 during which eight cases of breast lesions were diagnosed as of tubercular origin. RESULTS: Granulomas were seen in five cases while three cases revealed only few epithelioid cells, and necrosis was seen in all cases on fine-needle aspiration cytology. Histopathological evaluation was available in six out of the eight cases, while acid-fast bacilli were positive in three cases, the characteristic granulomas were seen in all the six cases evaluated. CONCLUSION: Significance of TB breast lies in the fact that it may masquerade as breast malignancy or pyogenic abscess. India is a developing country where TB is endemic, a high index of suspicion should be expressed in evaluating breast masses, and TB should be considered in the differential diagnosis.

Cytological diagnosis of crystallizing galactocele - report of an unusual case.

Crystallizing galactocele is a very rare entity which yields a viscous, chalky material on Fine Needle Aspiration Cytology (FNAC). FNAC is used both for diagnosis as well as treatment of this condition. We present here a case of 26 years old lactating female who presented with swelling in the right breast for 8 months. The swelling was firm, discrete, non-tender and mobile involving the upper inner quadrant of right breast. A diagnosis of benign breast disease, possibly fibroadenoma was made clinically. FNAC of the lesion yielded thick, milky and chalky material. Cytological smears showed numerous semitransparent crystals of varying size and shapes with angulated borders in a background of granular and amorphous debris along with frothy appearing micelles. These crystals show positive birefringence. Based on clinical history of lactation and typical cytological findings, a diagnosis of crystallizing galactocele was made. We report this case because of rarity of this condition and to the best of our knowledge, till date only five cases of crystallizing galactocele has been reported in medical literature.

Isolated lingual cysticercosis: A rare case diagnosed on cytology.

Cysticercosis is caused by larval stage of Taenia solium called cysticercus cellulosae. Cysticercosis most commonly infects skeletal muscles, subcutaneous tissues, brain and ocular tissue. On extensive search of literature, only around 64 cases of lingual cysticercosis have been reported till date. We report a case of cysticercosis of tongue in a 35-year-old male who presented with a painless, slowly growing swelling over the lateral border of tongue. Fine needle aspiration cytology revealed wavy integument of cysticercus cellulosae alongwith inflammatory cells. The findings were confirmed on histopathology. No other cystic swelling was encountered in the body on retrospective examination and investigations. This case is being presented on account of its rarity as well as the utility of FNAC as a primary diagnostic technique in evaluation of parasitic lesions.

Clinicopathological Study of Eosinophilic Cholecystitis: Five Year Single Institution Experience.

INTRODUCTION: Gallbladder diseases are very common in Northern India, most common of which is Chronic Cholecystitis. Rarely, histopathological diagnosis of Eosinophilic Cholecystitis (EC) is given when transmural cellular infiltrate consists of more than 90% eosinophils. AIM: To determine the prevalence and clinicopathological profile of eosinophilic cholecystitis at a tertiary care hospital of New Delhi. MATERIALS AND METHODS: This was a retrospective clinicopathological study done on twenty two cases of eosinophilic cholecystitis over a period of five years from January 2011- December 2015. In cases diagnosed histopathologically as eosinophilic cholecystitis, clinical details were obtained from hospital records and slides were retrieved. Various histologic features, pattern of the inflammatory infiltrate and association of EC with other medical diseases, drugs and allergic states were evaluated. RESULTS: Out of a total of 1370 cholecystectomy specimens received during five year period, Eosinophilic cholecystitis was diagnosed in 22 (1.6%) of the specimens. Clinically, seven of these patients had a clinical diagnosis of acute cholecystitis. Patient's age ranged from 25-64 years and male to female ratio was 1:2.7. Most common symptom reported was abdominal pain. Most of the cases showed gallstones radiologically (90%) while only two cases showed peripheral eosinophilia (9%). Histologically, mucosal and muscular eosinophilic infiltrate was seen in 72.6% of the cases. No association with drug therapy, allergies or other pre-existing medical conditions was noted. CONCLUSION: EC is a relatively uncommon entity in which histopathology remains the main stay of diagnosis. Although the presentation may be similar to general cholecystitis, if a postoperative histopathological diagnosis of EC is made, then the patient must be investigated thoroughly to rule out other associated disease conditions, which may have a worse prognosis than cholecystitis itself.

Unusual Histology in Hodgkin's Lymphoma: Report of an Interesting Case.

Hodgkin's lymphoma has a significant presence in the Indian subcontinent. Microscopically, the hallmark of Hodgkin's lymphoma (HL) is the Hodgkin and Reed-Sternberg (HRS) cell, which is usually surrounded by a cellular infiltrate of non-malignant inflammatory cells that constitute the majority of the tumor tissue. Cells which are known to be histologic mimics of HRS cells include immunoblasts, plasmablasts and rarely dendritic cells. We report a case of a 70-year-old male who presented with fever and lymphadenopathy. In the present case, the large cells with prominent nucleoli stained positively for both CD15 and CD30 and hence the possibility of angioimmunoblastic lymphadenopathy which was considered on the H&E-stained sections was excluded. In addition, noteworthy microscopic features in this case were angiogenesis and the presence of mast cells, both associated with a poor prognosis. The clinical impression was that of disseminated tuberculosis, but on histopathology, the final opinion was 'Hodgkin's lymphoma not classifiable with an unusual histology'. The aim of reporting this case is to highlight the unusual presentation in the form of prominent angiogenesis and mast cell infiltration in a case of HL, which is indicative of a poor prognosis.
