Article Abstract
Cytology by fine-needle cytology is indispensable for diagnosing head and neck tumor, especially for thyroid nodule. There are two methods of fine needle cytology; one of fine-needle aspiration cytology (FNAC and another of fine-needle non-aspiration cytology (FNNAC). These previous procedures has each disadvantage such as the mixing of blood or low yield of cells. We proposed a new technique: selective low-pressure fine needle aspiration cytology (SLOP-FNAC) to overcome the backwards of previous procedures. We used the scoring system by Mair et al. to evaluate smear quality of specimens obtained with FNNAC and SLOP-FNAC. SLOP-FNAC smears exhibited higher scores in amount of cellular material, degree of cellular degeneration and cell yield, and retention of appropriate architecture compared to FNNAC smears. The SLOP-FNAC smears scored significantly higher for amount of cellular material and retention of appropriate architecture evaluated ( = 0.0261 and = 0.0024, Student's -test). SLOP-FNAC may be a useful cell sampling technique that reduces blood contamination while securing a high cell yield with maintaining tissue structure.
The most prevalent form of thyroid cancer is papillary thyroid carcinoma, of which warthin-like papillary thyroid carcinoma (WLPTC) is an uncommon variant. The symptoms, diagnosis and course of treatment for this subtype of papillary thyroid cancer are comparable to those of the classic variety. It is usually associated with Hashimoto's thyroiditis and is considered to have a favourable prognosis.
The thyroid is a rare site for finding tumor metastases. Renal, colorectal, pulmonary, and mammary origin are the most frequent primary neoplasms. Clinical suspicion, early diagnosis, and active surveillance are important during follow-up.
Background: Cysticercosis, a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium, predominantly affects cerebral and ocular tissues. The subcutaneous manifestation of this disease is a relatively uncommon clinical occurrence. Previously very few or no cases of cysticercosis presenting as subcutaneous solitary painful swelling have been reported in the literature.
Unlabelled: SARS-CoV-2 mRNA vaccines induce robust and persistent germinal centre (GC) B cell responses in humans. It remains unclear how the continuous evolution of the virus impacts the breadth of the induced GC B cell response. Using ultrasound-guided fine needle aspiration, we examined draining lymph nodes of nine healthy adults following bivalent booster immunization.
Parathyroid adenoma is a common endocrine disorder, but its intrathyroid presentation is relatively rare. The traditional approach, such as thyroid blind lobectomy, is the most frequent modality of treatment due to the possible unclear localization of the adenoma in the preoperative workup. This increases the risk of unnecessary probability of hypothyroidism.
