Extra-ocular sebaceous carcinoma - A rare case report.

Sebaceous gland carcinoma is a rare and aggressive skin cancer derived from the sebaceous glands. Sebaceous carcinomas are divided into those occurring in ocular (75%) and extra-ocular locations. A 45-year-old female patient presented with rapidly growing swelling over the upper back region. It was provisionally diagnosed as an infected sebaceous cyst, and an excision biopsy was received in the pathology department. Histopathology was reported as sebaceous carcinoma, Grade II, Stage P T3 Nx. Immunohistochemistry was positive for epithelial membrane antigen. Sebaceous carcinoma accounts for 0.2-4.6% of all malignant cutaneous neoplasms, and the estimated rate of occurrence is only 1-2 per 1 million individuals per year. These tumors frequently present with a painless sub-cutaneous nodule, but they can also present as pedunculated lesions, irregular mass, or diffuse thickening of the skin. Hence, they are misinterpreted as other benign tumors or inflammatory conditions, thereby leading to delay in diagnosis, inappropriate treatment, increased morbidity, and mortality.

Abdominal scar endometriosis: A case report and review of literature.

Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. Abdominal wall or cutaneous endometriomas are quite uncommon with an incidence of less than 1%. Abdominal wall endometrioma can occur in a previous surgical scar, commonly following obstetrical and gynecological surgeries. Cutaneous endometriosis is difficult to diagnose because of its nonspecific symptoms and is often confused with other dermatological and surgical diseases thereby delaying the diagnosis and management. We are reporting a case of scar endometriosis at the site of previous cesarean scar involving the rectus sheath. The pathogenesis, diagnosis, and treatment of this rare condition are being discussed. Awareness of the clinical features and presentation of this rare condition is essential for timely diagnosis and management.

Primary Thyroid Lymphoma Diagnosed on Rapid Onsite and Cytology: A Rare Case Report.

Introduction: Rapid on-site evaluation (ROSE) is an essential component of thyroid cytopathology, particularly important in thyroid lymphoma, anaplastic carcinoma, metastasis to avoid unnecessary surgery. Follicular epithelial neoplasms are the most common tumors arising from the thyroid, whereas primary thyroid lymphomas are uncommon, accounting for less than 5% of all thyroid malignancies. Case description: A 45-year-old male patient presented to our ENT outpatient department with swelling in the anterior neck for 3 years duration. Non-aspirational needling was done along with rapid on-site evaluation using 1% aq. toluidine blue and was reported as Malignant thyroid neoplasm- possibility of Non-Hodgkin lymphoma (NHL). Cellblock sample also confirmed as B-cell NHL followed by Immunohistochemistry. Discussion: Primary thyroid lymphomas (PTL) are uncommon malignant neoplasms. They represent < 5% of all thyroid malignancies and 1-2% of all extra-nodal lymphomas. If diagnosed cytologically, unnecessary surgery can be avoided in thyroid lymphoma. ROSE helps in the rapid diagnosis and sample adequacy. Cellblock can avoid the biopsy procedure used for confirmation and subtyping of lymphoma.

Granulomatous cheilitis of Miescher: a rare entity.

BACKGROUND: Granulomatous cheilitis (GC) is a rare entity of unknown etiology. It is a chronic inflammatory disorder with a predilection for young females. It is characterized by asymptomatic unrelenting swelling of lips. It is a monosymptomatic form or an incomplete variant of Melkersson-Rosenthal syndrome (a triad of recurrent orofacial swelling, relapsing facial paralysis, and fissuring of the tongue). CASE PRESENTATION: We herewith report a case of a 27-year-old female, presenting with persistent upper lip swelling, for 3 months. Biopsy from the lesion revealed features of granulomatous cheilitis. CONCLUSION: GC should be considered in the differential diagnosis of unrelenting swelling in the lip. Spontaneous remission is rare, and recurrences are common. Corticosteroids used for treatment provide temporary improvement.

Applicability of On-Site Evaluation of Cervical Cytology Smears Stained with Toluidine Blue to Reduce Unsatisfactory Results.

INTRODUCTION: Carcinoma of the uterine cervix is a major health problem faced by Indian women. Screening techniques like visual inspection with acetic acid, Lugol's iodine, Papanicolaou smear, and human papillomavirus DNA testing have been suggested. Pap smear is a simple, safe, cost-effective, and reliable technique used for screening cervical lesions. Rapid on-site evaluation (ROSE) using the 1% aq. toluidine blue staining method has been less studied in cervical cytology. MATERIALS AND METHODS: Our study was a prospective study done over a period of 2 years. All the cervical cytology smears were reported as per the Bethesda system 2014. Rapid stain using aqueous toluidine blue (1%) and conventional Pap stain was done on the smears received. RESULTS: We evaluated a total of 1,300 cases, with 97.6% satisfactory samples. The spectrum of cases included 96.3% of negative for malignancy cases (including bacterial vaginosis, trichomonas, candida, and atrophic smears), atypical squamous cell of undetermined significance and atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion in 0.5% cases, low-grade squamous intraepithelial lesion and high-grade intraepithelial lesion in 0.3% cases, squamous cell carcinoma in 0.3% cases, and atypical glandular cells/adenocarcinoma in 0.2% cases. Turnaround time was within 48 h in 77% cases. With rapid stain, our unsatisfactory rate was reduced from 12% to approx. 2.4%. CONCLUSION: ROSE has been attempted on routine FNA cytology samples with success. However, the use of ROSE in cervical cytology has not been attempted to date. Lower unsatisfactory rate is an important indicator for the successful implementation of cervical cancer screening technique.

Diagnostic value of platelet indices in COVID 19 infection: a case-control study from a single tertiary care center.

Introduction: Platelets are not only involved in hemostasis and coagulation, but play a significant role in innate immunity and inflammatory response. Excess production of cytokines and acute phase reactants affect megakaryopoiesis resulting in the release of immature platelets from the bone marrow altering platelet indices. Aim: To study platelet indices in RT-PCR-proven COVID patients and non-COVID patients. Methods: A case-control study was conducted on 199 COVID-19 patients and 198 normal individuals. Blood samples were analyzed in an automated hematology analyzer. The platelet indices like platelet count, mean platelet volume (MPV), platelet distribution width (PDW), platelet large cell count (PLCC), and platelet large cell ratio (P-LCR) were compared among two groups. Results: Platelet count in COVID-19 patients were significantly low (p<0.01) compared to controls, and a significant number of COVID-19 patients had thrombocytopenia. Plateletcrit (PCT) was also significantly decreased in COVID-19 patients compared to non-COVID individuals. MPV, PDW, and PLCR were significantly (p<0.05) high in COVID-19 patients in comparison to controls, but was not significantly raised in a large number of cases. In contrast, there were no significant differences in platelet large cell count (PLCC) values between COVID-19 cases and non-COVID-19 controls. Conclusion: Platelet indices like platelet count, PCT, MPV, PDW, and P-LCR are significantly altered in COVID-19 infection and thereby can be used as biomarkers in COVID-19. Further research is needed to find if these simple, cost-effective parameters can be used to predict the severity and prognosis in COVID-19 infection.

Effect of 4-Week Heartfulness Meditation on Stress Scores, Sleep Quality, and Oxidative and Inflammatory Biochemical Parameters in COVID-19 Patients after Completion of Standard Treatment - A Randomized Controlled Trial.

Context: COVID-19-affected patients showed increased stress, impaired sleep quality, altered complete blood count, and increased inflammatory and oxidative parameters. Yoga is an add-on nonpharmacological treatment that is established to normalize the abovementioned parameters. Heartfulness meditation is a form of Raja yoga. Aims: The present study aimed to study the effects of 4 weeks of heartfulness meditation on the abovementioned parameters in COVID-19 patients following treatment completion. Settings and Design: The present study was a randomized controlled trial carried out in the Department of Physiology, AIIMS, Mangalagiri, Andhra Pradesh. Subjects and Methods: Out of 50 COVID-19 treatment-completed patients recruited for the study, 25 were randomly assigned to the study group who received 4-week app-based heartfulness meditation. Other 25 patients were assigned to the control group who received app-based relaxation for 4 weeks. Perceived stress score, Pittsburgh Sleep Quality Index questionnaire, baseline cardiovascular parameters, complete blood count, serum cortisol, inflammatory parameters, oxidative stress parameters, and antioxidant parameters were assessed before and after 4 weeks of intervention in both the groups. The outcome assessor was blinded in the present study. Statistical Analysis Used: The mean difference between the two groups was tested using the Student's t-test or Mann-Whitney U-test based on data distribution. Effect of intervention was analyzed using paired Student's t-test for dependent samples test or Wilcoxon signed-rank test based on data distribution. Results: The groups were comparable before intervention for all the variables. After 4 weeks of intervention, we observed a significant decrease in stress, circulating cortisol, inflammatory markers, and oxidative stress biomarker in both the groups. Further, we observed improved sleep quality and antioxidant biomarkers in both the groups. These beneficial alterations following intervention were high in the study group compared to the control group. Conclusions: Our results suggest that app-based heartfulness meditation/relaxation can be used as a nonpharmacological adjuvant to hasten the recovery process in patients who have completed the COVID-19 treatment protocol. Beneficial effects in subjects practicing heartfulness meditation were more than that observed in subjects practicing relaxation.

ROSE in Rosai-Dorfman-Destombes (RDD) disease: a cytological diagnosis.

BACKGROUND: Rosai-Dorfman-Destombes (RDD) is also known as sinus histiocytosis with massive lymphadenopathy (SHML). It is a benign proliferative disorder of histiocytes, affecting lymph nodes, rarely with extra-nodal involvement. Rapid on-site evaluation (ROSE) with fine-needle aspiration cytology (FNAC) can be utilized as a minimally invasive investigation to avoid unnecessary surgery of this self-limiting disease. CASE PRESENTATION: A 65-year-old female presented with complaints of bilateral cervical lymphadenopathy since 1 year. Rapid on-site stain with FNAC from bilateral cervical lymph nodes revealed features of Rosai-Dorfman-Destombes (RDD) disease. CONCLUSION: FNAC with rapid on-site evaluation can provide a simple and cost-effective method for looking at the unique cytological features of the disease and act as a first-line investigation.

Degos disease: a case report and review of the literature.

BACKGROUND: Degos disease is a very rare syndrome with multisystem vasculopathy of unknown cause. It can affect the skin, gastrointestinal tract, and central nervous system. However, other organs such as the kidney, lungs, pleura, and liver can also be involved. CASE PRESENTATION: A 35-year-old Hindu woman presented to our dermatology outpatient department with complaints of depigmented painful lesions. A skin punch biopsy taken from the porcelain white atrophic papules which revealed features of Degos disease. CONCLUSION: The diagnosis of Degos disease is usually based on the presence of the pathognomonic skin lesions and a tissue biopsy demonstrating a wedge-shaped area of necrosis with thrombotic occlusion of the small arterioles. No specific treatment is currently available for this disease.

Phaeoacremonium species detected in fine needle aspiration: a rare case report.

BACKGROUND: Fine needle aspiration cytology (FNAC) with rapid on-site evaluation has a great potential for the diagnosis of fungal lesions and other opportunistic infections. Fungal infections have been in increasing trend in the past two decades due to immunosuppression, travel, and environmental exposure. Human disease caused by Phaeoacremonium species is rare and was first reported in 1974 as subcutaneous tissue infection in a renal transplant recipient. CASE PRESENTATION: We report a case of subcutaneous tissue swelling in a 67-year-old male, wherein FNAC was done with incidental detection of the fungus (Phaeoacremonium spp). CONCLUSION: There are very few reported cases of subcutaneous infection in humans by Phaeoacremonium spp. Clinical suspicion and FNAC can play an important role in early detection of the fungus, prevent spread, and facilitating early treatment.
