Correlations between histological subtypes and neurocognitive assessment of language area tumors. Our 43 case series and review of the literature.

BACKGROUND: Brain tumor location is related with specific, focal neurological impairment, but also with more diffuse, generalized and subtitle neurocognitive dysfunctions. For a better evaluation of these cases, we need a specific battery of tests. Beside the impact of preoperative status on surgical decision, the quantification of postoperative function alteration is essential in neurorehabilitation. PATIENTS, MATERIALS AND METHODS: We proposed a battery of tests to assess the neurocognitive function, with an accent on language adapted to Romanian population. The 43 cases included in the study were tested preoperatively, seven days postoperatively and at one month, and correlated with the images and histological results. RESULTS: At admission, from all participants, 11.6% were affected across all measured items and 6.9% on none of them. A rate of impairment significantly higher, four or more items, was observed in glioblastoma (GB) cases (23.3%) in contrast with low-grade glioma (LGG) (0%), meningioma (0%) and metastases (6.9%). From all cases, we performed seven awake craniotomies. At one-month evaluation, general decrease in neurocognitive function was observed in 20.93% cases, among them 88.88% being GB and favorable outcome in 32.55% patients with dominance of LGG and meningioma cases. CONCLUSIONS: A neurocognitive assessment of brain tumor patients is important for preoperative and postoperative evaluation and secondary adjustment of the surgical resection in order to improve or, at list, meantime the initial status. The role and the link between the histological type and tests alteration were observed. The results can be used for a better understanding and management of language area tumors.

A novel combination of double primary malignancies: penile carcinoma and glioblastoma. A series of two cases.

AIM: Penile squamous cell carcinoma (pSCC) and glioblastoma (GB) are rare malignant tumors that develop especially in the elderly. The aim of our paper is to present two patients diagnosed and treated for a cerebral GB developed after a prior pSCC and to discuss the possible mechanism of their association. PATIENTS, MATERIALS, AND METHODS: The medical records of 632 patients admitted for a GB in the Department of Neurosurgery, "Prof. Dr. Nicolae Oblu" Emergency Clinical Hospital, Iasi, Romania, between April 2010 and April 2018, were retrospectively searched for those having a prior histological proven cancer. The review found only two patients (0.31% of all cases with GB) and their demographics, clinical presentation, medical history, treatment and pathological diagnosis were reviewed and discussed. RESULTS: Both patients were 65-year-old on their admission in the Department of Neurosurgery. Their prior penile tumors were both located at the penis glans. In both cases, the histopathological exam revealed a penile keratinized squamous cell carcinoma stage T1aN0M0 at the moment of their first urological diagnosis. At the time of the neurosurgical evaluation, brain radiological investigations demonstrated right frontal cystic neoformation in the first case, and a right frontal-parietal solid, expansive lesion for the second patient. The patients underwent subtotal surgical excision of their brain masses. The histopathological exam revealed in both cases a World Health Organization (WHO) grade IV GB. CONCLUSIONS: This is the first clinical report of a new association between pSCC and subsequent development of GB in a series of two patients. Both our patients developed a prior pSCC without any lymph node and distant metastasis at their first diagnosis and this situation reinforces the idea that this type of cancer has a good prognosis and that the patient can develop a second cancer during his post-penectomy life, probably due to a genetic predisposition, post-therapeutic effects, life style factors (smoke effects), sporadic association, or due to the common embryological origin of the nervous and skin tissues.

Cytological, histopathological and immunological aspects of autoimmune thyroiditis: a review.

Autoimmune thyroiditis (AT) is a disease that may be associated with many other autoimmune endocrine and non-endocrine disorders. This disease is mediated by both humoral and cellular mechanisms and it is the result of combined effects of human leukocyte antigen (HLA) class II genes and non-HLA genes polymorphisms. The clinical course of AT is variable and may be characterized by spontaneous remission and by irreversible thyroid insufficiency as the consequence of atrophic and fibrous transformation of the thyroid gland in other cases. In this paper, the AT's etiology and immunological mechanism along with its cytological and histopathological features are reviewed in order to increase our understanding about the mechanism involved in pathogenesis of this disease and to open new directions of investigations that will be useful in a better clinical practice.

Inflammatory juvenile compound conjunctival nevi. A clinicopathological study and literature review.

AIM: The conjunctival nevus affecting children and adolescents is a rare condition and the literature showed only few reports on this issue. The aim of this article is to determine the histopathological features for the correct diagnosis of an inflammatory juvenile compound nevus of the conjunctiva (IJCNC) in order to make the difference between this tumor and other lesions, like conjunctival melanoma or lymphoma, very similar from a gross point of view. This article is a clinical pathological study of two cases of IJCNC with particular histopathological characteristics, who were admitted at the 2nd Ophthalmology Clinic, "Prof. Dr. Nicolae Oblu" Emergency Clinical Hospital, Iasi, Romania, over a period of five years (from July 1, 2012 to June 30, 2017). Both patients were adolescents, a boy (13-year-old) and a girl (12-year-old). Both lesions were bulbar juxtalimbal located and grew in size over one year. Seen at slit-lamp biomicroscopy, the first one presented as a non-pigmented lesion, while the second was a pigmented nevus, but their dimensions did not exceed 10 mm in diameter. From a histopathological point of view, both of them showed a nested junctional growth pattern, along with intra- and subepithelial location, of the nevomelanocytes. Tumoral cells demonstrated different degrees of atypical cytology, but in the second case, it was more obvious. Microscopic examination also revealed epithelial cystic inclusions, and prominent inflammation in the stroma of these two nevi. One of the cases presented heavy inflammation that took the form of lymphoid follicles and sheets of eosinophils, but the other showed only diffuse inflammation with lymphocytes plasma cells, and eosinophils within its stroma. The immunohistochemical characterization (anti-melan A, anti-S100 protein and anti-cytokeratin AE1÷AE3 antibodies) of the tumoral cells helped to the diagnosis. CONCLUSIONS: IJCNC represent a small group of nevi that develop in adolescents and have some particular histopathological features. The pathological diagnosis is difficult as the microscopic features are very similar to a conjunctival melanoma, but a detailed microscopic examination, immunohistochemical stainings and the young age of the patient could help in establishing the benign nature of these lesions.

A 16-year retrospective study of dacryocystitis in adult patients in the Moldavia Region, Romania.

PURPOSE: Chronic dacryocystitis (CD) is an inflammation of the lacrimal sac and nasolacrimal duct with a long-standing evolution. The aims of this study were to analyze the epidemiology and to evaluate the histopathological features and the chronic inflammation score (CIS) system of chronic dacryocystitis in the region of Moldavia, Romania, over a period of 16 years. METHODS: We conducted a retrospective descriptive analysis of all pathological reports of chronic dacryocystitis from the Department of Pathology, "Prof. Dr. Nicolae Oblu" Emergency Clinical Hospital, Iasi, Romania, between January 1, 1999 and December 31, 2015, with the final application of CIS. We also recorded the demographic information of patients and lesion localizations. RESULTS: Eighteen cases of CD were identified, with a female:male ratio of 8:1. Patient median age was 66.27 years (range 33-83 years), 55.55% being in their eighth and ninth decade of life. A non-systemized growth trend starting with 2002 could be identified. Microscopically, several histopathological features were identified, some of them being associated: epithelial lining hyperplasia with pseudopapillary folds (77.77% of the cases), epithelial invaginations in the submucosa (11.11%), squamous metaplasia (16.66%) or partial denudation (33.33%). The sac wall revealed chronic diffusion (88.88%) or nodular lymphocytic inflammation (11.11%). 5.55% of cases presented fibrosis in the lacrimal sac wall with few lymphocytes. Applying CIS system, the majority of cases (13 patients, 72.22%) were identified with moderate chronic inflammation, only one case (5.55%) pointed out a mild degree of inflammation with a CIS<3, but four (22.22%) cases showed severe inflammatory changes with a CIS>6. CONCLUSIONS: In our region, CD is more frequent in senior women, probably due to their deficient immune system. Histological specimens of CD are not commonly found in practice of pathologists, but when the histological sections are analyzed they reflect a multitude of aspects that need to be known in order to guide ophthalmologists in their practice. In our region, CD is more frequent in senior women, probably due to their deficient immune system and to the specific anatomy of their nasolacrimal duct. The histological appearances varied from patient to patient and even in the same patient varied from one area to another. There were histopathological changes indicating adaptive changes, which could lead to the development of malignant tumors at this level. Therefore, there is a need for patient education with CD both in terms of ophthalmic hygiene and in what regards possible complications in the absence of a regular presentation to the ophthalmologist.
