Adenoid basal carcinoma cervix - A rare epithelial neoplasm.

ABSTRACT: Adenoid basal carcinoma of the uterine cervix is a rare epithelial neoplasm. Adenoid basal carcinoma constitutes less than 1% of all cervical adenocarcinomas and has a favorable prognosis. Adenoid basal carcinoma is assumed to arise from a multipotential basal or reserve cell layer in the cervical epithelium. We report a case of adenoid basal carcinoma of the uterine cervix with complaints of bleeding per vagina in a 40-year-old female. The carbohydrate antigen 125 level was elevated (100 U/ml), and the MRI abdomen and pelvis revealed increased signal intensity in the anterior lip of the cervix. The local examination revealed thickening of the anterior lip of the cervix and induration in the left fornix. The patient was diagnosed with carcinoma cervix stage IB2 (FIGO Stage). The patient was operated by a radical robotic hysterectomy. Microscopic examination revealed small basaloid tumor cell nests with peripheral cell palisading and microcyst formation. The tumor cells showed p63 immunoreactivity in basaloid tumor cells and were negative for CD117 and S-100P. This tumor should be differentiated from adenoid basal cell hyperplasia, which has a favorable outcome, and adenoid cystic carcinoma, with a dismal course.

Highly cellular leiomyoma - A great histopathological masquerader of endometrial stromal sarcoma.

ABSTRACT: Leiomyoma is the most common benign uterine tumor, whereas endometrial stromal tumors are rare uterine tumors with limited clinical experience. The distinction between highly cellular leiomyoma and endometrial stromal sarcoma can pose a diagnostic challenge to the pathologists as both these tumors have considerable overlapping features on histology.

Progressive disseminated histoplasmosis in idiopathic CD4 lymphocytopenia an underdiagnosed combination - a case report.

Progressive disseminated histoplasmosis (PDH) usually presents as fever, anemia, leukopenia, hepatosplenomegaly, lymphadenopathy and pulmonary symptoms. There are few reports on the association of idiopathic CD4 lymphocytopenia (ICL) with histoplasmosis. We describe a 65-year-old female presented with a history of fever, papulo-nodular rash and significant weight loss and diagnosed as progressive disseminated histoplasmosis. All immunocompromised conditions were ruled out. In addition, her 2 consecutive CD4 counts were below 300. The patient was diagnosed with PDH associated with ICL. The patient showed significant improvement with liposomal amphotericin B and itraconazole. Absolute CD4 counts should be done in all cases of progressive disseminated histoplasmosis even in HIV negative individuals to rule out associated ICL.

Risk Stratification of Breast Fine-Needle Aspiration Biopsy Specimens Performed without Radiologic Guidance by Application of the International Academy of Cytology Yokohama System for Reporting Breast Fine-Needle Aspiration Cytopathology.

BACKGROUND AND OBJECTIVE: The International Academy of Cytology (IAC) Yokohama system for reporting breast fine-needle aspiration biopsy (FNAB) cytopathology has been proposed to standardize breast FNAB reporting. The aim of this study was to categorize breast FNAB cases performed by palpation without radiological guidance according to the IAC system, establish the risk of malignancy (ROM) for the categories and assess the system's utility, pitfalls, and implications in low-resource/financial constraint settings. METHODS: A retrospective analysis of palpation-guided FNAB of breast lesions performed without radiological guidance between January 2016 and December 2019 was carried out and was correlated with follow-up biopsies wherever available. A total of 1,089 cases were recategorized using the IAC Yokohama system. Histopathology follow-up was available for 400 cases. The data were analysed for ROM, positive predictive value (PPV), and negative predictive value (NPV). RESULTS AND DISCUSSION: Out of 1,089 cases, 4.3% (n = 47) cases were categorized as insufficient, 82% (n = 893) as benign, 2.8% (n = 31) as atypical, 2.7% (n = 29) as suspicious of malignancy, and 8.2% (n = 89) as malignant. Some 400 cases had a follow-up biopsy, based on which, the ROM for the categories were 33.3%, 0.4%, 37.5%, 96%, and 100%. The NPV for the benign category was 99.6%. The PPV of the malignant category was 100%, that of combined suspicious of malignancy and malignant categories was 99%, and of combined atypical, suspicious of malignancy, and malignant was 90.6%. CONCLUSION: The IAC Yokohama system is useful in standardizing the reporting of cytopathology of breast lesions. FNAB with radiological guidance is ideal but in cases of finance/resource constraints, FNAB by palpation alone is satisfactory if the test result is in the benign, suspicious of malignancy, or malignant categories, which constitute 91.5% of the cases in this study. A repeat ultrasound-guided FNAB and/or core needle biopsy should be recommended for cases in the insufficient/inadequate or atypical categories.

Giant Endometrial Polyp in a Postmenopausal Woman.

Endometrial polyps are the benign localized overgrowth of endometrial tissue composed of a variable amount of gland, fibroblast-like spindle cells stroma, and thick-walled blood vessels. They develop as a result of unbalanced estrogens and progestin. Polyps greater than 4 cm are considered giant polyps. We report a case of giant endometrial polyp in a postmenopausal woman who presented with postmenopausal bleeding without any history of hormone or drug intake. However, the possible cause may be the age and use of phytoestrogens in the daily routine diet for a long time.

Bronchial Carcinoid Tumour as a Rare Cause of Cushing's Syndrome in Children: A Case Report and Review of Literature

Cushing's syndrome (CS) is rare in childhood and adolescence. The most common paediatric cause of CS is exogenous administration of glucocorticoids; either topical, inhaled or oral corticosteroids. Endogenous causes can be classified into adrenocorticotropic hormone (ACTH) independent and ACTH dependent causes. Herein, we report our experience of managing a 12 year old girl who presented with features of CS and was found to have an ectopic, ACTH-secreting bronchial carcinoid tumour, which was resected surgically. Our patient was managed successfully by multidisciplinary approach and has recovered from hypertension and Cushing's habitus. The English language literature was searched from 2019 back, using PubMed, Google and Google Scholar. Keywords used for the search were; "Ectopic ACTH syndrome (EAS) in children", "bronchial carcinoid in children" and "Cushing's Syndrome in children". Children with bronchial carcinoid tumours causing EAS were identified. Case variables such as age, sex, type of carcinoid, investigations, surgery, recurrences and outcome were reviewed. Fourteen cases of paediatric bronchial carcinoid producing ACTH were found with a mean age of 15.8 years and female preponderance. Most of the patients had a right lung lesion and histological appearance was typical of carcinoid tumour. Bronchial carcinoid is extremely rare in children and only 4% are associated with CS. The postoperative treatment of CS is challenging with a high prevalence of hypertension, increased body mass index and visceral fat mass, impaired cognitive function and decreased quality of life. A careful follow up is indispensable for monitoring recurrence of carcinoid and complete remission of CS.

Clinical and laboratory correlates of selective autonomic dysfunction due to Ross syndrome.

Ross syndrome is diagnosed by the presence of the characteristic triad of segmental anhidrosis, depressed deep tendon reflex, and tonic pupils. It is a rare, misdiagnosed autonomic disorder with less than 80 cases reported in the world literature. Two representative cases of Ross syndrome are presented with their laboratory correlates and relevant review of literature. Both cases (aged 35 and 58) presented with complaint of decreased sweating over one half of the face and ipsilateral upper limb and trunk and contralateral lower limb. There was compensatory increased sweating and hyperpigmentation over the remaining parts of the body. The duration of symptoms was 2 years and 15 days. The patients had variegated skin color as per the above distribution and hyporeflexia in lower limbs. One patient also had Holmes-Adie pupil. Iodine test showed hypohidrosis in the described areas, which was confirmed by skin biopsy in both cases. The patients were treated symptomatically with incomplete relief. The authors aim to highlight this rare disorder that can be one of the causes of pathological sweating encountered in general practice and the challenges in its management.
