Velscope guided oral cancer screening: A ray of hope in early oral cancer diagnosis.

Context: Early oral cancer diagnosis is an important factor in reducing cancer-associated mortality and morbidity. Traditional oral cancer screening by Conventional Oral Examination (COE) is limited. A new approach in this regard is the use of "optical biopsy systems" like VELscope. Aims: Hence, this study aimed to determine the diagnostic value of VELscope, an autofluorescence-based handheld device in detection of dysplasia and oral squamous cell carcinoma (OSCC) in general oral potentially malignant disorder. Settings and Design: A prospective, cross-sectional study was conducted at a tertiary hospital in western Maharashtra, India. Materials and Methods: Thirty patients with presence of clinically suspicious oral lesions were included, and for each lesion, both the COE and Autofluorescence Examination by VELscope were carried out at the same appointment by different experts. All lesions were biopsied and histopathological findings were documented and analyzed. Statistical Analysis Used: Sensitivity, specificity, positive predictive value and negative predictive value were estimated to determine the accuracy of VELscope examination analysis outcome. Results: The study included a total of 30 subjects including 19 (63.33%) males and 11 (26.66%) females. Autofluorescence examination by VELscope (AFV) revealed Autofluorescence Loss in 24 (80%) patients, while 6 (20%) patients showed Autofluorescence Retained. Comparison between the "high-risk lesions" (moderate/severe dysplasia and OSCC) and "low-risk lesions" (no/mild dysplasia) showed a 90.47% sensitivity but only 44.44% specificity. Conclusions: The findings of our study indicate that although AFV cannot be a substitute for COE, it can be used as a potential complementary diagnostic aid in surveillance of the high-risk patient population.

Acral Nodular Melanoma Presenting With Rapid Progression.

Melanoma is a malignant tumor that is derived from melanocytes of the skin and other sites. Melanoma accounts for 1% to 3% of all malignancies and 1% to 2% of all cancer deaths worldwide. We are presenting a case of a 42-year-old female who presented to the surgery department with a growth over the right heel since 18 months, with a history of trauma to the site. The lesion showed rapid progression with a large mass and secondary skin ulceration and sloughing. A PET scan showed an enhancing lesion on the right heel measuring 11 mm in thickness. There was no evidence of any systemic organ or any lymph node metastasis. Surgical excision and reconstruction on the part of the heel by a local flap with sural graft with split-thickness skin grafting was done. The excised growth was sent for histopathology. The histopathological diagnosis of nodular melanoma (NM) of the heel was given. We are presenting this case for its clinical, histopathological, and surgical management.

Leptomeningeal Carcinomatosis Secondary to Esophageal Cancer Diagnosed on Cytology.

Esophageal carcinoma is considered a common malignancy across the globe. These patients usually present with an advanced stage of the disease at the time of diagnosis. Herein, we report a 55-year male patient who presented with leptomeningeal carcinomatosis, detected on cerebrospinal fluid (CSF) cytology in a case of adenocarcinoma lower third esophagus. On radiological imaging, he also had extensive metastatic deposits in the liver, pleura, and regional and paravertebral lymph nodes.

Primary primitive neuroectodermal tumor of the kidney.

Renal primitive neuroectodermal tumor (PNET) is a rare entity. It should be differentiated from other primary renal malignancies. The differentiation of the malignant small round cell tumors may be challenging; however, it is essential for better management of the patient. We report a 45-year-old male having complaints of pain in the abdomen, hematuria, and mass in the abdomen for 6 months. Abdominal and pelvic sonography finding showed cystic-solid, right renal mass suggestive of malignancy. On histopathology diagnosed as malignant small round blue cell tumor suggestive of primitive neuroectodermal tumor. On immunohistochemistry, CD99 positivity confirmed the diagnosis of primary PNET of the kidney. We are presenting this case for its rarity, clinical presentation, and pathological findings.

Gestational Trophoblastic Disease - Clinicopathological Study at Tertiary Care Hospital.

INTRODUCTION: Gestational Trophoblastic Disease (GTD) is a term used for a group of pregnancy-related tumours. These consist of various tumours and tumour like lesions characterized by proliferation of trophoblastic tissue. Amongst GTD, hydatidiform moles are the most common form. These lesions sometimes may develop into invasive moles, or, in rare cases, into choriocarcinoma. AIM: To study the clinicopathologic characteristics and prevalence of different forms of gestational trophoblastic disease in a tertiary care hospital. MATERIALS AND METHODS: The present study was descriptive, observational, analytical type done in Department of Pathology at tertiary care hospital from May 2012 to April 2016. All cases clinically suspected of GTD were included and confirmation was done by histopathological study on H&E stained slides. The cases of GTD were classified according to WHO classification. Detailed histomorphological features and beta human Chorionic Gonadotropin (hCG) levels were correlated. RESULTS: During study period, 18345 deliveries were reported; out of which 77 cases were diagnosed as GTD. Almost 97.40% cases were of hydatidiform moles, 1.30% cases of choriocarcinoma and 1.30% cases of Placental Site Trophoblastic Tumour (PSTT). Among the cases of hydatidiform mole 57.34% were complete mole and 41.33% cases were of partial mole. The common clinical presentation was per vaginal bleeding and amenorrhea. The blood group A was most commonly observed in patient (49.35%). In majority of cases beta hCG levels were between 50,000 to 100000 mIU/ml. The correlation between beta hCG level and GTD were done. CONCLUSION: Pregnant females clinically presenting with abnormal vaginal bleeding must be evaluated for GTD. Histopathological examination is helpful for confirmatory diagnosis. Follow up of such patients is essential for early detection of malignant trophoblastic tumours.

Sialosis: Cytomorphological significance in the diagnosis of an uncommon entity.

A diffuse, chronic, usually bilateral, noninflammatory, nonneoplastic enlargement of major salivary glands is termed as Sialosis or Sialadenosis. It is an extremely uncommon cause for enlargement of the parotid gland. We hereby present a case of a 45-year-old female patient having a swelling at the left preauricular region. The swelling was gradually increasing in size since 6 months. On clinical examination, the swelling was 3 cm × 3 cm, mobile, and nontender. On ultrasonography, it was suggestive of benign parotid lesion or parotitis with cervical lymphadenopathy. On fine needle aspiration cytology, it was suggestive of sialadenosis. This is an extremely rare salivary gland lesion with specific cellular features. It is very important to distinguish sialadenosis from other causes of enlargement of the parotid gland as treatment modality differs.

Primary Squamous Cell Carcinoma of Urinary Bladder - A Rare Histological Variant.

Primary squamous cell carcinoma of urinary bladder is a rare histological variant of epithelial bladder tumours. Histopathological types are associated with significant disease outcome, so it is essential to find, on microscopy the exact type of urothelial carcinoma. Herewith, we present a 70-year-old male having 3 months history of difficulty in micturition, reduced frequency of urine and associated pain. On Contrast Enhanced CT scan abdomen pelvis, showed irregular large urinary bladder mass with hydroureter and hydronephrosis. Internal iliac group of lymphnodes was enlarged. On histopathology diagnosed as pure squamous cell carcinoma of urinary bladder grade II with muscle invasion. We are presenting this case for its clinical, radiological and histopathological findings.

Otocephaly: Agnathia- Microstomia-Synotia Syndrome- A Rare Congenital Anomaly.

Otocephaly is a rare malformation characterized by the association of agnathia (agenesis of mandible) or mandibular hypoplasia, melotia (anteromedial malposition of ears), microstomia (small mouth), aglossia or microglossia (absent or rudimentary tongue). This rare anomaly of the ventral portion of first brachial arch is a consequence of failure of migration of neural crest cells from hind brain. It leads to the development of maxillary and mandibular prominences and starts to develop at the fourth and fifth week of gestation. We hereby present the autopsy findings of a fetus of 28 weeks gestation abortus having otocephaly without holoprosencephaly.

Multicentric Metaplastic Breast Carcinoma with Squamous Differentiation.

Metaplastic breast carcinoma is a rare primary breast malignancy. A 45-year-old female patient presented with multicentric lumps in left breast of 6 months duration and history of axillary lymphadenopathy of 2 months duration. Mammography revealed two high density masses with ill defined margins. Fine needle aspiration cytology was positive for duct carcinoma cells. Histo pathologic examination, reported as "Multicentric infiltrating duct carcinoma with squamous differentiation left breast", grade 2. Immunohistochemistry revealed negativity for ER, PR and positivity for HER-2/neu. We are presenting this rare case for clinical, radiological, histopathological and immunohistochemical study.

High-grade myxofibrosarcoma-presented as a large mass of right upper arm.

Myxofibrosarcoma is one of the rare soft tissue sarcomas. We present a case of a 65-year-old male having large soft tissue mass over right upper arm associated with surface ulceration. On histopathological study tumor was diagnosed as myxofibrosarcoma - high grade according to modified FNCLCC grading system. Like many other tumors of connective tissue, soft tissue sarcoma exhibits high recurrence. In our case, tumor showed features of high grade with local recurrence, large size; however, no evidence of metastasis was noted. For this unpredictable clinical behavior, we are presenting this case.

Primary Angiosarcoma of the Breast: An Uncommon Histopathological Subtype.

Primary angiosarcoma of the breast is extremely rare malignant tumour of the breast. The cytological and radiological findings are often non specific for diagnosis. Histopathology plays an important role in diagnosis and grading of tumour. Herewith we present a case of 55-year-old postmenopausal woman having history of rapidly enlarging right breast lump with prominent vascularity and associated bluish discolouration of overlying skin. Mammography shows ill defined mass lesion. Fine needle aspiration cytology was done which showed haemorrhagic aspirate with few clusters of highly pleomorphic neoplastic cells. Patient underwent modified radical mastectomy. On histopathological evaluation it showed primary angiosarcoma of the breast, poorly differentiated, grade-III. We are presenting this extremely rare malignancy of breast for its clinical, cytological and histopathological findings.

Male breast cancer: presenting as synchronous, large, bilateral masses.

Male breast cancer is a very rare neoplasm which accounts for 1% of all breast cancers. A 70-year-old male presented with a rapidly growing, bilateral breast masses with large size, surface ulceration and bloody discharge. Synchronous bilateral breast cancer was diagnosed by using fine needle aspiration cytology, mammography, ultrasonography and incisional biopsy. Histopathological studies revealed invasive ductal carcinoma (not otherwise specified), which was of grade III in left breast and of grade II in right breast. We are presenting this case with its clinico-pathological findings, as synchronous bilateral breast cancer occurs extremely rarely in males.

Adrenocortical carcinoma presenting as a rupture and extensive retroperitoneal haemorrhage.

Adrenocortical carcinoma (ACC) is an extremely rare tumour. We are reporting a 45-year-male patient who had a history of sudden severe worsening epigastric pain and fullness in abdomen, with giddiness. The radiological investigations showed a large right suprarenal mass with extensive destruction and retroperitoneal haemorrhage, with extra capsular, periportal and liver metastases. Exploratory laparotomy was done for excisions of mass and surrounding tissue. On histopathological examination, diagnosis was given as Adreno Cortical Carcinoma with capsular, vascular, and soft tissue nodular involvement.

Fine needle aspiration diagnosis of carotid body tumor in a case of multiple paragangliomas presenting with facial palsy: a case report.

BACKGROUND: Carotid body tumors (CBTs) constitute the most common extraadrenal paragangliomas. Many lesions diagnosed as CBTs by fine needle aspiration (FNA) cytology are clinically unsuspected. The main differential diagnosis is a thyroid neoplasm. The location of the mass in the lateral neck with prolonged history, hemorrhagic FNA and cytologic features resembling the endocrine neoplasm help in arriving at a suggestive diagnosis of paraganglioma. CASE: A 32-year-old male presented with left-sided facial palsy and swelling in the left side of the neck of 8 months' duration. The FNA sample was hemorrhagic and showed loosely arranged groups and acini formed by round to oval cells. A diagnosis of CBT was suggested. It was supplemented by additional noninvasive methods, such as ultrasonography of the neck region with color Doppler, computed tomography and magnetic resonance imaging of the brain, which also revealed a neoplasm suggestive of carotid body tumor in the right side of the neck and neoplastic lesion in the left cerebellopontine angle, suggestive of paraganglioma. CONCLUSION: FNA, with the other noninvasive radiologic investigations, plays an important role in the diagnosis of CBT. We present this case of multiple paragangliomas for its unusual presentation and FNA diagnosis.

Eosinophilic enteritis presenting as a rare cause for ileo-ileal intussusception.

Eosinophilic enteritis, a relatively rare entity, usually involves gastric antrum or proximal small bowel. Our case is rarer in its involvement of the distal small bowel and presents unusually as intussusception. The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed, surgical modality is the treatment of choice. In our case, the patient presented with acute intestinal obstruction due to intussusception and emergency laparotomy with ileoileal anastomosis was done. Histopathology confirmed the diagnosis as eosinophilic enteritis. This case with such a presentation is discussed here.
