Objective: Our study aimed to characterize alteration in the immunohistochemical expression of estrogen, progesterone and androgen receptor in the tumour cells of primary pleomorphic adenomas and recurrent pleomorphic adenomas.
Methods: A retrospective study of data including 30 cases of primary pleomorphic adenomas (PA) without recurrences and 15 cases of recurrent pleomorphic adenomas were examined (RPA). RPA included 8 males and 7 females. Immunohistochemical expression of estrogen, progesterone and androgen receptor was examined in the selected cases. The percentage of slides was semi-quantitatively assessed by two independent observers and scores were given. The statistical analysis included the use of descriptive statistics and proportional frequencies.
Results: AR expression was identified in 12 (40. %) out of 30 cases of (PA) pleomorphic adenomas and 7 of 15 cases recurrent pleomorphic adenomas (RPA) (46 %). The results showed that ER and PR expression were negative in PA and RPA.
Conclusion: Androgen receptors might have role in pathogenesis of PA and RPA. Estrogen and progesterone receptors have no role in development of recurrent pleomorphic salivary adenoma.

(1) : Salivary gland tumors (SGTs) are a rare and diverse group of neoplasms arising in the parotid, submandibular, sublingual, and minor salivary glands distributed throughout the upper aerodigestive tract. Given the rarity and complexity of MSGTs, understanding their epidemiology across diverse populations is crucial for improving diagnostic and therapeutic strategies. (2) : A retrospective analysis involving 45 patients diagnosed with malignant salivary gland tumors and treated with curative intention between 1 July 2016 and 1 July 2021 in a tertiary academic hospital was performed.

Pleomorphic adenoma of the lacrimal gland (PALG) is a benign neoplasm typically presenting with gradual, painless globe displacement and/or lid swelling. We report an atypical case of PALG in a 53-year old male presenting acutely, mimicking orbital cellulitis. Imaging demonstrated an extraconal rim-enhancing soft-tissue lesion medial to the left lacrimal gland, involving superior rectus and levator palpebrae superioris.

A lipoblastoma is a benign tumor of adipocytes originating from embryonic white fat and occurs in the pediatric population. Congenital lipoblastomas, however, are rare, and the incidence of these tumors in neonates is unknown. Due to their rare presentation, congenital oral lipoblastomas can, firstly, pose diagnostic challenges for the pediatrician and must be differentiated from the more commonly seen oral lesions in the newborn and other rare malignant growths.

Gestational trophoblastic neoplasms are tumors that occur during pregnancy, while non-gestational trophoblastic tumors have a similar histology but are present outside of gestation. Literature reports several cases of non-gestational trophoblastic tumors of primary pulmonary origin, which pose diagnostic challenges and are associated with a poor prognosis. This report details a case of somatic high-grade carcinoma with trophoblastic differentiation primarily manifesting in the left lung with recurrent pneumothoraces.

Background: Prognostication of atypical spindle cell neoplasms, including atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS), is challenging; outcomes vary widely, and further identification of prognostic features is crucial.
Objective: To evaluate prognostic factors that may portend worse outcomes in patients with AFX and PDS.
Materials And Methods: A retrospective chart review of patients with AFX and PDS was conducted.
