Pilar cysts are common benign cysts of follicular origin that typically arise in areas of skin containing dense hair follicles such as the scalp. Here we describe a unique case of a young woman who was found to have a pilar cyst on the dorsum of her hand, a rather atypical location given the relative lack of pilosebaceous units. This case illustrates the variability in pilar cyst presentation and the importance of considering a pilar cyst in the differential diagnosis of a patient presenting with a tumor of the dorsal hand.

We present successful surgical treatment of a patient with chronic kidney disease (CKD) and hyperparathyroidism undergoing renal replacement therapy. At baseline, parathyroidectomy via cervical access was performed for parathyroid adenomas. After 6 years, clinical and laboratory relapse of disease required thoracoscopic resection of atypically located anterior mediastinal adenoma. This case demonstrates that this disease is one of the most difficult in modern medicine requiring a special approach in diagnosis and treatment. Patients with CKD and hyperparathyroidism need for follow-up, control of total and ionized serum calcium, inorganic phosphorus and parathormone, osteodensitometry, ultrasound and scintigraphy of thyroid and parathyroid glands, and, if necessary, CT or MRI of the neck and chest organs.
Представлен случай успешного хирургического лечения пациентки с хронической болезнью почек (ХБП) и гиперпаратиреозом, находящейся на заместительной почечной терапии методом программного гемодиализа, — удаления аденом околощитовидных желез (ОЩЖ) сначала путем тотальной паратиреоидэктомии из шейного доступа, а затем, через 6 лет, при возникновении клинико-лабораторного рецидива заболевания, путем торакоскопического удаления атипично расположенной аденомы переднего средостения. Представленное наблюдение служит доказательством того, что это заболевание является одним из самых непростых в современной медицине и требует особого подхода в диагностике и лечении. Пациенты с ХБП и гиперпаратиреозом нуждаются в постоянном динамическом наблюдении: контроле уровня общего и ионизированного кальция, неорганического фосфора и паратгормона в сыворотке крови, периодическом выполнении денситометрии скелета, ультразвукового исследования, сцинтиграфии щитовидной железы и околощитовидных желез и при необходимости компьютерной томографии или магнитно-резонансной томографии органов шеи и грудной клетки.

Lymphoplasmocytic plaque in children (LPC) is a rare and distinctive skin disorder primarily affecting the pediatric population. Characterized by its unique histopathological features, the condition manifests as well-defined plaques with a predominance of lymphocytes and plasma cells infiltrating the dermis. Despite its limited prevalence, recognizing this entity is crucial for accurate diagnosis and appropriate management of affected patients. We report the case of a 10-year-old male presenting with LPC in the extensor surface of the upper arm, a rarely reported location, treated with both topical and intralesional corticosteroids resulting in partial improvement.

We present a case of a 56-year-old man who committed suicide using a captive-bolt gun, pressed against the left side of his chest. As the victim worked as a butcher, slaughtering livestock, he owned a captive-bolt gun. Just before committing suicide, he received a disturbing phone call from a person to whom he owed money. The autopsy revealed a 12-mm wound in the left pectoral region with two symmetrical, oval soot deposits. The wound extended through the fifth left rib, the pericardium, and the inferior portion of the anterior wall of the left ventricle. There was a partial-thickness tear in the left aspect of the interventricular septum with associated contusion. About 300 ml of the blood was found within the pericardial sack and about 1200 ml in the left pleural cavity. Atypical location (left chest vs. head), absence of previous suicide attempts and suicide note, and the apparent immediate provoking event suggest abrupt rather than premeditated suicide.

We report the case of a 37-year old patient with no particular past medical history presenting to the Ophthalmology Department for lens correction. Examination of the right eye showed corrected visual acuity of 6/10e, refractive error of -1.50 (-6,25 to 56°); the examination of the anterior segment objectified lenticular coloboma in the superior temporal area with zonular deficiency ranging from 8h to 11h and opacity of the crystalline. The examination of the iris and fundus examination were normal. Left eye exam was normal. Colobomas are congenital malformations of the eye secondary to an abnormal closure of the foetal fissure. Lenticular coloboma is rare, secondary to uveal coloboma resulting in indentation of the lens periphery. It usually occurs in the inferonasal region. The peculiarities of our case study is the occurrence of lenticular coloboma in the superior temporal area. It is essential to search for opacity of the crystalline in patients with other colobomatous abnormalities and associated ocular malformations such as cataract, microphthalmia or ectopia of the crystalline.

Osteoid osteomas are benign and nonprogressive lesions. The clinical presentation of osteoid osteoma is typical with night pain responsive to nonsteroidal anti-inflammatory agents. The typical radiological appearance is lucent nidus and adjacent reactive sclerosis. The most traditional management of osteoid osteoma is surgical removal which is associated with significant morbidity. This article aims to demonstrate our single-center experience of 55 patients with osteoid osteoma treated with percutaneous radiofrequency ablation (RFA).
Fifty-five symptomatic patients who were seen at our orthopedics outpatient clinics, diagnosed with osteoid osteoma, and referred to interventional radiology department between May 2015 and April 2019 were enrolled. The nidus size, pain numeric rating scale score, and intramedullary edema diameter before and after RFA were compared. Clinical and technical success, intervention-related complications, and need for subsequent ablation were recorded.
Of the 55 patients, including 12 pediatric cases, 6 had atypical locations such as metatarsal, vertebra, and scapula, while 1 case had osteoid osteoma with multiple nidus. The mean age was 18.5 ± 9.6 years. Preintervention maximum nidus diameter, pain score, and edema diameter were significantly lower in postintervention measurements (p < 0.001). Technical success rate was 98.1%, and clinical success was 96.36%. Severe complication occurred in one patient with soft tissue burn and osteomyelitis.
This is one of the largest series of osteoid osteoma treated with RFA done in a single center with atypical cases. In conclusion, RFA is safe and effective in both pediatric and adult patients with rare complications even in challenging cases with atypical locations.

Extralobar sequestrations are rare congenital malformations of the lung. They are usually located between the diaphragm and left lower lobe and receive their blood supply from the aorta. We report a case of extralobar sequestration in an atypical location with a pulmonary arterial feeding vessel. An 18-year-old woman presented with an abnormality on chest X-ray. Chest computed tomography revealed a lung field not communicating with the bronchus between the upper and lower right lung lobes. Three-dimensional reconstruction computed tomography demonstrated a feeding artery from the pulmonary artery draining into the pulmonary vein. We diagnosed her with extralobar sequestration and resected the sequestered lung using video-assisted thoracic surgery. Therefore, three-dimensional reconstruction computed tomography helped identify the abnormal blood vessels, and video-assisted thoracic surgery may be useful in the treatment of extralobar sequestration.

Angiofibromas in the head and neck region usually arise in the nasopharynx, but may also occur elsewhere. This study aims at evaluating the incidence and clinical features of extranasopharyngeal angiofibroma (ENA).
Systematic review of the literature (Medline® and Google™ ) up to 31 December 2015.
174 cases of ENA were retrieved from a total of 170 publications. In contrast to former publications and previous understanding, the nasal septum was by far the most common site of the disease. Four patients had a congenital lesion, the oldest patient was 87 years old (mean: 28.7 years; median: 23 years). Male gender was predominantly affected, but the sex ratio was more balanced (2.13:1) than in previous reports in the literature until 12/2015. The majority of patients presented with nasal obstruction, either in combination with epistaxis (25.8%) or other symptoms (12.6%). Symptoms had developed within 13.1 months on average (median: 4 months). Brisk bleeding resulted in 11 of 43 biopsy procedures. Surgical resection as first-line therapy was performed in 170 patients. A tumour regrowth within 12 months was registered in four patients.
The increasing awareness of ENA and the willingness to publish case reports-not only in Medline-listed journals-resulted in a significant increase of published case reports lately. Although extremely rare, ENAs have to be taken into account in the differential diagnosis of unclear masses, particularly in adult patients presenting with a rapidly developing nasal obstruction resulting from a nasal septum tumour. Female gender or normal vascularity does not exclude the diagnosis. Transnasal resection is sufficient in most cases, and recurrences are rare. Pathologists as well as clinicians should consider ENA in their differential diagnosis of any mass of the upper airway.

BACKGROUND: Cystic lesions associated with the blockage of Bartholin gland ducts are frequently seen, but occurrence outside the normal vestibular localization is quite rare.
METHODS: A 16-year-old patient presented with a localized cystic lump approximately 4 cm in size on one of her labia minora. After an excision, she was diagnosed with an atypically localized Bartholin cyst.
CONCLUSIONS: It is very difficult to make an early diagnosis for an atypically localized Bartholin cystic lesion in adolescence; it can be diagnosed only after a pathological examination. In the differential diagnosis of a vulvar lump, an atypically localized Bartholin cyst should also be considered as a possibility.
