Breast metastasis from extra-mammary malignancy is rare. Based on the literature an incidence of 0.4-1.3% is reported. The primary malignancies most commonly metastasizing to the breast are leukemia-lymphoma, and malignant melanoma. We present a case of metastasis to the breast from a pulmonary adenocarcinoma, with extensive micropapillary component, diagnosed concomitantly with the primary tumor. A 73-year-old female presented with dyspnea and dry cough of 4 weeks duration and a massive pleural effusion was found on a chest radiograph. Additionally, on physical examination a poorly defined mass was noted in the upper outer quadrant of the left breast. The patient underwent bronchoscopy, excisional breast biopsy and medical thoracoscopy. By cytology, histology and immunohistochemistry primary lung adenocarcinoma with metastasis to the breast and parietal pleura was diagnosed. Both the primary and metastatic anatomic sites demonstrated histologically extensive micropapillary component, which is recently recognized as an important prognostic factor. The patient received chemotherapy but passed away within 7 months. Accurate differentiation of metastatic from primary carcinoma is of crucial importance because the treatment and prognosis differ significantly.

We and others have previously shown that increased expression and altered compartmentalization of γ-tubulin may contribute to tumorigenesis and tumor progression (J. Cell Physiol. 2009;223:519-529; Cancer Biol. Ther. 2010;9:66-76). Here we have determined by immunohistochemistry the localization and cellular distribution of γ-tubulin in clinical tissue samples from 109 non-small cell lung cancer (NSCLC) cases. The expression and distribution of γ-tubulin protein and transcripts was also determined in the NSCLC tumor cell lines NCI-H460 (HTB-177) and NCI-H69 (HTB-119) by immunocytochemistry, quantitative immunoblotting and reverse transcription quantitative real-time PCR (RT-qPCR). Polyclonal and monoclonal anti-peptide antibodies recognizing epitopes in the C- or N-terminal domains of γ-tubulins and human gene-specific primers for γ-tubulins 1 (TUBG1) and 2 (TUBG2) were used. In non-neoplastic cells of the airway epithelium in situ, γ-tubulin exhibited predominantly apical surface and pericentriolar localizations. In contrast, markedly increased, albeit heterogeneous and variously prominent γ-tubulin immunoreactivity was detected in clinical tumor specimens and in the NCI-H460 and NCI-H69 cell lines, where tumor cells exhibited overlapping multi-punctate and diffuse patterns of localization. Co-expression of γ-tubulin and Ki-67 (MIB-1) was detected in a population of proliferating tumor cells. A statistically significant increase of γ-tubulin expression was found in Stage III compared to lesser stage tumors (p<0.001 v. Stages I/II) regardless of histological subtype or grade. By quantitative immunoblotting NCI-H460 and NCI-H69 cells expressed higher levels of γ-tubulin protein compared to small airway epithelial cells (SAEC). In both tumor cell lines increase in TUBG1 and TUBG2 transcripts was detected by RT-qPCR. Our results reveal for the first time an increased expression of γ-tubulin in lung cancer.

Carcinoid tumour of the appendix in children: a case report

Carcinoids are the most common tumours of the appendix. These tumours show prevalence in white children. The clinical presentation of the appendiceal carcinoids is similar to that of acute appendicitis, although in many cases the tumour is diagnosed incidentally during an operation. The diagnosis should be confirmed histologically. The prognosis in patients with local disease is excellent. In small lesions isolated appendicectomy is considered as the most appropriate treatment, while in larger lesions right colectomy should be performed. We report a case of a carcinoid tumour in the tip of the appendix of a thirteen year old girl which was diagnosed intraoperatively. The patient received isolated appendicectomy due to the small size of the lesion. Ten years after the operation there is no evidence of recurrence or metastases, and the patient is considered free of disease.

We present an unusual case of solitary renalmass that histological examination followingnephrectomy confirms that it was aneurofibroma. Neoplasmatic markers though, werefound elevated and chromosomal analysisrevealed a Karyotype similar to the one foundin adenocarcinomas of the kidney.

Cecal epiploica appendix torsion in a female child mimicking acute appendicitis: a case report

Acute appendicitis is the most common cause of the right lower quadrant acute abdominal pain in children. Some other conditions including cecal epiploica appendix torsion, can simulate acute abdomen. Epiploica appendix torsion usually occurs in the sigmoid colon and rarely in the cecum of adult males. In children, this entity is extremely rare and may represent a diagnostic and therapeutic dilemma. We report a case of an 8-year-old Greek girl, presented with signs and symptoms mimicking acute abdomen. Our patient is the younger one among the other four with cecal epiploica appendix torsion that had been reported in the literature.

Asymptomatic Glomus Tumor of the Mediastinum

Meletios A. Kanakis; Nikoletta Rapti; Maria Chorti; Achilleas Lioulias

Glomus tumors are rare benign neoplasms that predominate in limbs. Infrequently, they can occur in a wide anatomic distribution, to include sites not known to contain glomus cells. Although glomus tumors are usually small, pain and tenderness are common clinical symptoms. We report the case of a 69-year-old man with an asymptomatic large mediastinal glomus tumor, who underwent surgical resection.

Patient: Female, 60 Final Diagnosis: Inflammatory pseudotumor of the lung Symptoms: Cough dry • fever Medication: — Clinical Procedure: — Specialty: — Objective: Rare disease Background: Inflammatory pseudotumor of the lung involves a benign, non-neoplastic lung lesion of unknown etiology. Case Report: We present a case of a 60-year-old female smoker who had been under intermittent immunosuppressive medication for discoid lupus, who was admitted to hospital with fever of 39.5°C of 10-day duration, not responding to an oral cephalosporin. Chest CT examination showed a cavitating opacity in the upper zone of the left lung. It was not feasible to establish a diagnosis based on clinical and laboratory testing nor based on CT scanning and bronchoscopy. Thus, the patient underwent left thoracotomy and sphenoid resection of the lesion, which was sent for biopsy. The histopathologic features aided by immunohistochemical staining proved the lesion to be an inflammatory pseudotumor of the lung. Conclusions: The case is reported because of the extremely rare radiologic presentation of the development of a lung pseudotumor emerging as a cavitated lesion, which relapsed during the follow-up period while the patient was still under immunosuppressive medication.

Herpes simplex is an uncommon cause of lower respiratory tract infection that requires prompt diagnosis and treatment to prevent late complications. We report two cases with simultaneous herpes simplex virus infection of the lower respiratory tract and lung carcinoma. Cytology of bronchial brushing and washing fluids and postbronchoscopic sputum established the diagnosis, which was further corroborated by real‐time polymerase chain reaction. Diagn.

IntroductionCrohns disease (CD) can affect any part of the alimentary tract from the mouth to the anus, with most common site being the terminal ileum.Case presentationA child suffering from undiagnosed Crohn disease (CD), presented with an acute abdominal obstruction due to a large pseudopolyp in the jejunoileal area. At laparotomy, a jejunoileal segment of 45 cm, containing multiple areas of damage to the small intestine, was excised and a primary end – to – end anastomosis was performed.ConclusionThe coexistence of an intestinal pseudopolyp with undiagnosed Crohns disease may be the cause of acute abdominal obstruction in children.

We report the case of a 3-yr-old boy who presented an acute right hydrocele. A rapid scrotal swelling under tension developed the first hours and the child complained for discomfort especially during palpation of the scrotum. Three days later, surgical exploration revealed an incomplete torsion of a communicated and pedunculated peritoneal sac arising from the tunica vaginalis testis.The present case report represents the eleventh report of torsion of processus vaginalis saccular protrusion in the literature, being unique due to painless hematocele.
