Distinguishing Features

Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands. However, it is a rare entity in larynx. Laryngeal cases are frequently misdiagnosed with other malignancies and they are under-reported. So, recognizing the clinical and histological features of this tumor is essential. Laryngeal mucoepidermoid carcinoma can arise in supraglottis, glottis and subglottis. Generally, it presents as a submucosal mass; therefore, progressive symptoms without any identifiable lesion in laryngoscopy must be well considered. The prognosis is somehow dependent on the histological features. In high-grade tumors, recurrence is more common and radical surgery with radiotherapy is recommended. In this paper, we provide a thorough literature review on mucoepidermoid carcinoma in the larynx. The most important distinguishing features of mucoepidermoid carcinoma and its two major differential diagnoses (squamous cell carcinoma and adenosquamous carcinoma) are clearly stated and pitfalls in true diagnosis of this tumor are discussed.

Carcinoma Of The Larynx

Twenty-one cases of mucoepidermoid-adenosquamous carcinoma (MEC/ASC) of the larynx and hypopharynx were collected and reviewed from the Armed Forces Institute of Pathology tumor registry from 1945 to 1979. This is the largest series of such lesions in this location reported to date. In addition, the literature was reviewed and 32 previous cases noted. The overall five-year survival was 77%, although low-grade mucoepidermoid carcinoma had a better survival than did adenosquamous—high-grade mucoepidermoid carcinoma.

Sarcomas of breast constitute less than 1% of all malignant breast tumours. Alveolar rhabdomyosarcoma (RMS) is very rare in breast with limited case reports in literature, and primary alveolar RMS arising from breast is still less common than metastatic RMS. Here, we report a case of primary bilateral alveolar RMS of breast in an adolescent female where the correct diagnosis was obfuscated by an overlap in the histological features of RMS and high-grade invasive ductal carcinoma.

Carcinoma Of Gallbladder

Adenocarcinoma is the most common variant of gallbladder carcinoma. Adenosquamous carcinoma and pure squamous cell carcinoma are rare variants accounting for only up to 3% of the tumors. Pure squamous cell carcinoma of the gallbladder is reported and its incidence is less than 1%. Usually they present at advanced stage and many of the times these are unresectable. Hence survival in patients with squamous cell carcinoma is less than adenocarcinoma, and carries a bad prognosis. We report a rare case of squamous cell carcinoma gallbladder, which was well differentiated, diagnosed early and resected completely. Postoperatively patient is planned for adjuvant chemotherapy.

Aims: To investigate the efficacy and safety of minimally invasive bronchoscopic interventions for patients with tracheobronchial mucoepidermoid carcinoma (MEC). Methods: Patients with tracheobronchial MEC were included in this retrospective study, and the clinical features, histologic grading, treatments, and cumulative survival rates were calculated. Patients were categorized into child (n = 16) and adult (n = 19) group according to their ages. Histologic grading, treatments, and survival status were compared between the two groups. Results: In pathology, high-grade MEC counts for 6.77% and 42.10% in the child and adult group, respectively. As tumor growth pattern was concerned, 93.33% and 21.05% tumors in the child and adult group present intratracheal type. Multiple bronchoscopic interventions were conducted, including rigid bronchoscopy, argon plasma coagulation (APC), dioxide carbon cryotherapy, and electric loop. Tumors could be removed by multiple bronchoscopic interventions. Bronchoscopy-associated complications were rare, including an oral mucosa injury and a glottis edema. In the child group, one patient underwent left upper lung lobectomy. In the adult group, lobectomy and/or chemotherapy and/or radiotherapy were conducted in seven patients. The 5-year survival rate was 100% and 68.90% in the child and the adult group, respectively. Conclusions: Almost all children have low-grade and intratracheal MEC; 2/5 adults have invasive high-grade MEC. Multiple bronchoscopic interventions are effective in erasing low-grade intratracheal MEC without severe complications. For high-grade invasive MEC, aggressive and comprehensive therapy should be considered.

Abstract Gorham-Stout disease (GSD) is a rare entity that destroys the bone matrix resulting mainly in osteolysis, pain and pathologic fractures among a broader clinical picture. We report a case of a 60-year-old female with a sudden discovery of pathologic fractures in the pelvis and the absence of the left femoral head. On biopsy, no cellular atypia was found, instead disturbed bone formation with prominent vascularity with scattered foci of necrosis & osteolysis, which lead to the diagnosis of GSD. Possible differential diagnoses were discussed and excluded. The patient was put on Bisphosphonate that led to a relative improvement in the symptoms. This disease needs a more thorough investigation to identify the key cause, what is beyond the scope of this report.

PURPOSE: To investigate whether the addition of cisplatin (CDDP) to hyperfractionation (Hfx) radiation therapy (RT) offers an advantage over the same Hfx RT given alone in locally advanced (stages III and IV) squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: One hundred thirty patients were randomized to receive either Hfx RT alone to a tumor dose of 77 Gy in 70 fractions in 35 treatment days over 7 weeks (group I, n = 65) or the same Hfx RT and concurrent low-dose (6 mg/m2) daily CDDP (group II, n = 65). RESULTS: Hfx RT/chemotherapy offered significantly higher survival rates than Hfx RT alone (68% v 49% at 2 years and 46% v 25% at 5 years; P = .0075). It also offered higher progression-free survival (46% v 25% at 5 years; P = .0068), higher locoregional progression-free survival (LRPFS) (50% v 36% at 5 years; P = .041), and higher distant metastasis-free survival (DMFS) (86% v 57% at 5 years; P = .0013). However, there was no difference between the two treatment groups in the incidence of either acute or late high-grade RT-induced toxicity. Hematologic high-grade toxicity was more frequent in group II patients. CONCLUSION: As compared with Hfx RT alone, Hfx RT and concurrent low-dose daily CDDP offered a survival advantage, as well as improved LRPFS and DMFS.

Primary squamous cell carcinoma of the renal parenchyma is an extremely rare entity. The diagnosis of squamous cell carcinoma of the renal pelvis is usually unsuspected due to the rarity and inconclusive clinical and radiological features. Most of the patients are diagnosed at an advanced stage and are with poor outcome. Radical nephrectomy is the mainstay of the treatment. We reported a case of squamous cell carcinoma of the kidney in a 50-year-old female who presented with the right sided abdomen pain. The patient was treated with radical nephrectomy.
