Introduction: Amongst all the malignant tumours, laryngeal cancer is found in 2.2% of males and 0.4% of females. Histopathologically, 90-95% of all laryngeal cancer is Squamous Cell Carcinoma (SCC). Tumour stage and cervical lymph node metastases are the most influential factors in determining a worsening prognosis. Aim: To investigate the relationship between perineural invasion, peritumoural inflammation, other commonly used prognostic parameters such as tumour stage, and cervical lymph node metastases in laryngeal SCC and contribute to the follow-up and treatment of patients. Materials and Methods: The pathology archive at Istanbul Sisli Hamidiye Etfal Education and Research Hospital was utilised for this research. Retrospective analysis was performed of data on 110 cases of laryngectomy and neck dissection specimens. Cases diagnosed as SCC were included in the study. Histopathologic analysis was conducted on the paraffin-embedded tissue sections of 110 cases. The data were encoded, transmitted to a computer, and analysed using SPSS ® 20.0. The Kruskal-Wallis H test was used to compare the groups. Statistical significance was considered to be p-value=<0.050. Results: The rate of cervical lymph node metastases was higher in the presence of perineural invasion, mild peritumoural inflammation, and advanced tumour stage. A statistically significant relationship was identified between perineural invasion, peritumoural inflammation, tumour stage, and the rate of cervical lymph node metastases in SCC of the larynx. Conclusion: Cervical lymph node metastases should be carefully investigated in the presence of perineural invasion and mild peritumoural inflammation in SCC of the larynx.

Glomus tumours are benign lesions which are frequently seen on hand (particularly subungual region). In this report a 52-year-old male patient with glomangiomyoma on the left forearm has been presented. With a preliminary diagnosis of haemangioma, a subcutaneous well-circumscribed nodular lesion of the patient was excised. On histomorphological examination glomus cells, vascular structures and spindle-shaped smooth muscle cells were seen around it. Immunohistochemistry of smooth muscle cells and glomus cells showed positivity for smooth muscle actin. By means of these findings, the patient was diagnosed with glomangiomyoma. Glomus tumours are rare in the forearm (In the literatüre there are two cases). Moreover, glomangiomyomas are the least common histomorphological type of glomus tumour and are generally seen in the lower extremity. In the literature, a few cases of glomangioma and solitary glomus tumour has been described on the forearm histologically and only a few glomangiomyoma cases on forearm location. We have presented the glomangiomyoma on the forearm as a rarely-seen case. Early diagnosis of the glomangiomyoma on the forearm is of importance for the prevention of morbidity.

Multicystic nephroma (MCN) is relatively a rare, nongenetic and benign lesion of the kidney which has a bimodal distribution. The congenital form is commonly seen under the age of 2. Adult-onset MCN is more often seen in women, especially in post menopausal females. The aetiopathogenesis of MCN is still unknown. Ovarian-like stroma of the tumour indicates the tumour originates from the mullerian tissue of the kidney. Hormonal theory is suggestive as the stroma of the tumour is positive for estrogen and progesteron. Preoperative diagnosis of MCN is difficult. Surgical approach is recommended both for the histological diagnosis and the treatment of the disease. We here present a 53-year-old female patient with MCN admitted to the urology clinic with left flank pain treated successfully with partial nephrectomy. No recurrence was noted after six months of clinical and radiological follow-up.

Malignant nerve sheath tumours (MPNST) are rare neoplasias and retroperitoneal cases are fairly rare and clinically difficult to be detected, but they are very agressive neoplasias. MPNST are frequently seen in head, neck and upper extremities. In patients with NF1; MPNST,a poor-prognostic lesion, may result from a malignant degeneration of a former plexiform neurofibroma. It is necessary to be aware of a potential malignancy in patients diagnosed with plexiform neurofibroma. We present a 21-year-old female with a diagnosis of MPNST. The patient was admited to the hospital because of a tumour in the subcutaneous region on her left buttock. The surgeon’s clinical diagnosis was lipoma. After the pathological examination of biopsy specimen, the lesion was identified as “plexiform neurofibroma” and then the patient was diagnosed with Neurofibromatosis Type 1 (NF1). Simultaneously, another mass on the retroperitoneal region was identified as malignant peripheral nerve sheath tumour (MPNST).
