RESUMEN

INTRODUCTION AND IMPORTANCE: Actinomycosis is a rare, chronic bacterial infection caused by Actinomyces species. While it commonly affects the cervicofacial region, thorax, and abdomen, appendicular involvement is extremely uncommon. This case report details the presentation, diagnosis, and management of a 45-year-old female patient with acute appendicitis secondary to actinomycosis. CASE PRESENTATION: A 45-year-old woman, with an 8-year intrauterine device history, presented with three-day right iliac fossa pain, vomiting, and stable vital signs. Laboratory tests revealed an inflammatory syndrome. Suspecting acute appendicitis, a CT scan confirmed a swollen 10 mm appendix. Laparoscopic surgery revealed a phlegmonous appendix, leading to an uncomplicated appendectomy. Pathological examination confirmed actinomycotic granules, supporting the diagnosis of actinomycosis appendicitis. The patient received 18 million units of intravenous penicillin G daily for 6 weeks followed by a 6-month course of oral amoxicillin (1 g three times daily) thereafter, showing favorable progression with no symptoms. Normal clinical and ultrasound follow-ups were observed at one year. CLINICAL DISCUSSION: Appendiceal actinomycosis is a rare condition. Women, especially those with intrauterine contraceptives, experience an increase in cases due to chronic inflammation. Typically underdiagnosed, actinomycosis mimics other conditions, presenting with nonspecific symptoms. Laboratory results offer limited assistance, and histological confirmation is crucial. Histopathological examination is mandatory for diagnosis confirmation. Management involves surgical resection and prolonged penicillin-based antibiotics, providing a favorable prognosis with low mortality. CONCLUSION: This case underscores the importance of considering rare etiologies, such as actinomycosis, in the differential diagnosis of appendicitis. Timely recognition and management are crucial for optimal patient outcomes.

RESUMEN

Pulmonary granular cells tumors (CGT) are rare tumors, that derive from Schwann cells. In the tracheobronchial and pulmonary tree, they remain a diagnostic challenge. There are no well-established criteria to differentiate between benign, atypical, and malignant GCT. Moreover, its real frequency in the respiratory tract is still unknown. Here, we represent 2 cases of bronchial and lung GCTs. We aim to highlight the frequency of all clinicopathological characteristics of this rare tumor in the tracheobronchial and pulmonary tree location based on our cases and the available literature in a large systematic review.

RESUMEN

BACKGROUND: The treatment of patients with locally advanced non-small-cell lung cancer is controversial. Surgery remains the gold standard, even in this group. Neoadjuvant chemotherapy could allow surgical resection in patients initially judged inoperable. METHODS: From January 2009 to May 2010, neoadjuvant chemotherapy was indicated in 27 patients with NSCLC (25 men, 2 women). Their mean age was 65 years. The stages were: IIB in 5, IIIA in 17 (6 in stage IIIAN2), IIIB in 2, and IV in 3. RESULTS: 23 patients received neoadjuvant chemotherapy, 2 refused induction treatment, and 2 had impaired status. The neoadjuvant chemotherapy regimen was gemcitabine-cisplatin in 17 patients and vinorelbine-cisplatin in 6. Only 5 patients underwent complete surgical treatment after induction: 1 in stage IIB, 1 in stage IIIAN0, 1 in IIIB, and 2 in stage IV (1 operated brain metastasis, and 1 operated adrenal metastasis). Surgical treatment was not achieved after neoadjuvant chemotherapy in 18 patients because of progressive disease. CONCLUSION: Neoadjuvant chemotherapy offers several potential benefits, but it may delay surgery or eliminate eligibility as a surgical candidate. Rigorous patient selection for this type of multimodal treatment is essential.
