Follicular thyroid carcinoma (FTC) is a well-differentiated malignancy, while insular thyroid carcinoma (ITC) is a very rare and poorly differentiated tumor. The present study reports a case of ITC arising within the background of FTC. A 52-year-old housewife presented with an anterior neck swelling for a duration of 6 months. An ultrasound examination revealed a well-defined solid nodule measuring ~58x37x28 mm in the mid-lower third of the right thyroid lobe, and two small nodules of <3 mm in size in the left lobe. Fine needle aspiration cytology of the lesion led to the suspicion of follicular neoplasm. A right thyroid lobectomy was performed, and the histopathological examination revealed poorly differentiated insular carcinoma arising in the background of FTC. As a result of this diagnosis, a completion thyroidectomy was performed. ITC is a rare and highly aggressive thyroid malignancy that is morphologically and biologically regarded as an intermediate between fully differentiated and undifferentiated/anaplastic thyroid carcinomas. In comparison to patients solely with follicular carcinoma, patients with insular carcinoma are older, more often male, have larger tumor sizes, are at greater risk of metastasis, and have a lower survival rate. Poorly differentiated ITC with follicular carcinoma is a very rare and aggressive condition that could be managed by thyroidectomy followed by radioiodine therapy. [ABSTRACT FROM AUTHOR]

The choice between nodulectomy and lobectomy for managing thyroid nodules is a subject of debate in the field of thyroid surgery. The present study aims to share the experience of a single center in managing solitary thyroid nodules through nodulectomy from January 2023 to October 2023. The inclusion criteria encompassed symptomatic or suspicious solitary nodules and medically necessitated cases. The extracted data included patient demographics, medical history, symptoms, diagnostic details, surgery indication, procedure outcome and histopathological findings. The follow-up included clinic visits and phone calls. The mean age of the patients was 36.64±11.63 years, with 85.0% females and 15.0% males. Predominantly, patients were housewives (58.5%). Neck swelling (62.3%) was the most common presentation. Ultrasound examination revealed mixed nodules in more than half of the cases (54.7%). Right nodulectomy was performed in 26 cases (49.1%) and left nodulectomy in 23 (43.4%), and four cases (7.5%) underwent isthmusectomy. The mean operation time was 36.04±9.37 min and no drainage tube was used in any of the cases. One case (1.9%) of seroma was the only observed complication during the observational period. Nodulectomy may be a suitable choice for managing benign, large, solitary thyroid nodules, small suspicious nodules or microcarcinomas. [ABSTRACT FROM AUTHOR]

Granulomatous mastitis (GM) in accessory breast tissue is rare. The present study aimed to report a rare case of GM in accessory breast tissue. A 39-year-old female patient presented with right axillary discomfort and swelling for ~5 days. On clinical examination, a tender, firm lump was detected in the right axillary region. The ultrasound showed diffuse parenchymal heterogeneity and surrounding edema in the right accessory breast associated with reactive axillary lymph nodes. Following unresponsiveness to conservative treatment, a surgical procedure was performed in the form of an excisional biopsy and the lesion was diagnosed as GM. During the six-month follow-up, there were no recurrences. The exact cause of GM remains uncertain and the etiology within accessory breast tissue is even less understood. Proposed mechanisms suggest that it may result from an exaggerated immune response triggered by various factors, such as infection, autoimmunity or hormonal fluctuations. GM in accessory breast tissue is a rare and challenging clinical condition to be diagnosed. Due to the rarity of this condition, it highlights the importance of including GM in the differential diagnosis of axillary masses. [ABSTRACT FROM AUTHOR]

Aggressive fibromatosis is a rare clonal proliferative tumor arising from mesenchymal cells in the fascia and musculoaponeurotic structures. The aim of the present study was to describe several cases of extra-abdominal recurrent aggressive fibromatosis. The present study was a single-center retrospective case series of patients with recurrent aggressive fibromatosis. The cases were managed at a single private facility. A total of 9 patients with recurrent fibromatosis were included. The mean and median ages of the patients were 29 and 30 years, respectively. In total, two thirds (66.67%) of the cases were female. A negative previous medical history was reported in 7 cases (77.7%), and diabetes and hypertension were reported in 1 case (11.1%). Overall, only 1 case (11.1%) had a family history of breast fibromatosis. The time interval between primary tumor resection and recurrent presentation was 28 months. In 6 cases (66.7%), the tumor was located in the extremities. Pain was the most common presenting symptom in 6 cases (66.7%). All patients had their recurring tumor surgically removed, followed by radiation in 5 cases. The resection margin was positive in 4 cases (44.4%). Each patient was subjected to a careful three-month follow-up for recurrences. On the whole, the present study demonstrates that despite the fact that several therapeutic approaches for extra-abdominal recurrent aggressive fibromatosis have been described in the literature, there is a significant likelihood of recurrence following resection.

Early diagnosis and appropriate staging workup are crucial for cancer patients. Whole-body magnetic resonance imaging (WB-MRI) has been proposed as another practical whole-body approach for assessing local invasiveness and distant metastases in patients newly diagnosed with cancer. The current study aimed to evaluate the efficacy of WB-MRI in assessing metastasis in patients newly diagnosed with cancer using histopathologic data as the reference method. A prospective observational study was performed from April 2018 to July 2020. MRI sequences were utilized to acquire anatomical and functional images in three orthogonal planes. The discovery was classified as nodal, skeletal and visceral metastases. Patient-based analysis was used for visceral metastasis and region-based for skeletal, systemic and lymph node metastases. A total of 43 consecutive patients (mean age, 56±15.2 years) were assessed successively. In 41 patients, there was a concordance between the WB-MRI and histological confirmation. The most prevalent site of metastasis was the skeletal system (18 patients). There were 12 individuals with liver metastasis, 10 with lung metastasis and 4 with peritoneal metastasis, with just one brain metastatic lesion found. On WB-MRI, 38 lymph node groups were deemed positive. Out of the total, 66 skeletal locations contained metastases. The accuracy of WB-MRI for nodal, skeletal and visceral metastases was (98.45, 100 and 100%, respectively). In conclusion, WB-MRI in three orthogonal planes, including the diffusion-weighted MRI with background body signal suppression sequence, may be utilized efficiently and accurately for assessing metastasis staging and may thus be utilized in patients with newly diagnosed cancer.

Key Clinical Message: Contraceptive implant migration is a rare complication associated with contraceptive implants: migration to the ulnar nerve, emphasizing the importance of accurate diagnosis, imaging, and a multidisciplinary approach to mitigate neurovascular risks during insertion and removal procedures. The case report demonstrates the necessity for careful removal techniques and thorough patient follow-up to ensure positive outcomes and prevent long-term nerve damage., There are some potential risks and complications associated with contraceptive implants, including neurovascular injury. The aim of this case report is to report a rare complication associated with contraceptive implants. A 32-year-old female, right-hand dominant, presented to the orthopedic clinic for the extraction of a contraceptive implant (Implanon) from her left arm. She reported intermittent numbness in the ring and little fingers. Upon examination, the Implanon was not palpable. Both Phalen's test and Tinel signs were negative. An x-ray of the arm revealed the implant's position. Under local anesthesia through a longitudinal incision, the Implanon was found within the perineurium of the ulnar nerve. Two weeks after the operation, the patient returned to the clinic. Upon examination, there were no indications of ulnar nerve neuropathy. If a patient undergoes subdermal implant-associated pain or is at risk of neurovascular damage during removal, it is advisable to refer the patient to a family planning specialist experienced in handling challenging implant removals, and subsequently to a peripheral nerve surgeon, to optimize outcomes. The migration of a contraceptive implant to the ulnar nerve is an exceedingly rare but possible complication., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).
