Parathyroid cysts are an uncommon entity. They are classified as functioning and nonfunctioning cysts. Cyst aspiration with detection of parathyroid hormone is a useful tool to confirm the diagnosis. Here, we report four cases of parathyroid cysts. One patient had a functioning cyst. Ultrasonography of the neck revealed a cystic lesion behind the left lobe of the thyroid gland in two cases and a right cystic thyroid nodule in two cases. The cysts exerted a mass effect on the adjacent structures in two cases without clinical compressive symptoms. Fine-needle aspiration with detection of parathyroid hormone in the cyst fluid was performed in one case (nonfunctioning cyst): intracystic parathyroid hormone level was high. Recurrence was noted 1 month after the cyst aspiration. All patients underwent surgical treatment. Our series is characterized by two cases of nonfunctioning intrathyroidal parathyroid cysts which are very uncommon. They are mistaken for thyroid cysts. After surgery, no recurrence was noted. We aim to describe the epidemiological, clinical, and paraclinical features of this condition as well as its therapeutic modalities.

A 13-year-old boy was referred to orthopedic surgery for chronic intermittent pain and swelling of the left knee. Initial imaging was consistent with osteochondritis dissecans of the femoral condyle. Follow-up imaging demonstrated unexpected progression, with a mass extending into the notch, replacing the anterior cruciate ligament, and eroding the femoral and tibial condyles.

Article Synopsis
- Kürsteiner canals (KC) are embryological remnants linked to parathyroid and thymic development, with ongoing research aimed at understanding their role in various parathyroid lesions and cysts.
- A study evaluated 62 cystic and 22 non-cystic parathyroid lesions over a 12-year period, identifying distinct KC phenotypes in relation to the presence of parathyroid hormone (PTH).
- The findings reveal that KC commonly appear in parathyroids, particularly in non-PTH cysts, and suggest that these manifestations may originate from KC, while PTH-positive cysts are associated with different characteristics.

Article Synopsis
- - Parathyroid cysts (PCs) are uncommon tumors mainly found in middle-aged women, causing symptoms like fatigue and bone pain due to hyperparathyroidism, often requiring surgical removal to prevent severe complications.
- - A case study discusses a 62-year-old woman with severe hypercalcemia and a cystic mass near the thyroid, where imaging helped lead to surgery that removed both the PC and a coinciding thyroid cancer.
- - The report emphasizes the need for accurate diagnostics and surgical approaches for managing both PCs and thyroid issues while exploring possible links between primary hyperparathyroidism and thyroid cancers.

A 56-year-old male presented with a longstanding, gradually enlarging, painful, skin lesion over the natal cleft. This was initially thought to be a pilonidal abscess but, following multiple surgeries, he was diagnosed with Stage IVb squamous cell carcinoma of the natal cleft skin with bilateral inguinal lymph node metastases and subcutaneous metastatic deposits. Complete surgical cure was not possible.
