Callus formation of the tibial hallux sesamoid mimicking a bone tumor

Sesamoid tumors of the hallux are rare, and their incidence and differential diagnosis have not been well described. We present a case with a bizarre callus formation of the medial sesamoid of the hallux that mimicked a bone tumor. After excision of the mass and related sesamoid, the patient remained asymptomatic during 3 years of follow-up.C1 Pamukkale Univ, Sch Med, Dept Orthopaed, Kinikli Denizli, Turkey.Pamukkale Univ, Sch Med, Dept Radiol, Kinikli Denizli, Turkey.Pamukkale Univ, Sch Med, Dept Pathol, Kinikli Denizli, Turkey

Pharyngeal thyroid: a case report

A 48-year-old woman presented with dysphagia. On examination of the pharynx, a mass was visible behind and adjacent to the right tonsil. It was excised and proved to be ectopic thyroid tissue

Intracranial Chondrosarcoma in a 22-Years Old Woman: Report of A Case

Background: Intracranial chondroid tumors are consist of less than 0.16% of all primary brain neoplasms. They are classified as mesenchymal, classic and myxoid according to their cytoarchitecture. They usually arise at the skull base from the cartilaginous synchondroses and the pluripotent mesenchymal cells of the overlying dura mater.Case: We present a 22-year old female patient, who had history of seizures for 10 years and recent increase in the frequency of the seizures. Cranial magnetic resonance imaging (MRI) demonstrated a well-demarcated, parasagittal left frontal mass, which compressed to the lateral ventricle. It was hypointense on T1-weighted and hyperintense on T2-weighted images and making an edema on the surrounding tissue. Gross total resection of the firm mass was performed with clear margins. The tumor was composed of lobules of mature-appearing hyaline cartilage. The tumor cellularity was increased, each lacuna contained one or two atypical chondrocytes which had two or more nuclei per cell. Neoplastic chondrocytes had plump and hyperchromatic nuclei. Mitotic rate was low and no atypical mitotic figures were noted. Neoplastic chondrocytes showed nuclear staining for S-100 protein, but not for pancytokeratin. Histopathologic examination revealed a classic low grade chondrosarcoma.Conclusion: Intracranial chondrosarcomas are rare malign tumors. We report a patient with a grade I intracranial chondrosarcoma of the classical subtype without any neurologic problem after complete surgical excision. She did not received any adjuvant therapy and 28 months follow-up showed no recurrence. So it seems that, especially in the low grade chondrosarcoma, radical neurosurgical resection is the first line of treatment, and if necessary adjuvant therapy can be planned

Following ICSI

Intracytoplasmic sperm injection (ICSI) is a widespread and powerful method enabling men with low sperm quantity and quality to become fathers. However, compared with naturally conceived children, there are increased risks of problems, such as congenital malformations, chromosomal abnormalities, infertility, epigenetic diseases, and delayed neuropsychological development in the offspring. We present the case of 6-year-old male patient born following ICSI with clinical and radiological features of Goldenhar syndrome as well as a history of surgery for unilateral cryptorchidism. His karyotyping showed a chromosomal constitution of 47, XXY. Clinicians should be aware of the risks of an increasing number of patients born following ICSI to maximize children's health and welfare
