The authors report a case of gangrenous acute appendicitis in the sac of an inguinal hernia (Amyand's hernia). After a review of the literature, they emphasise the extreme rarity of the case reported, they underline how the clinical picture is highly similar to that of a strangulated inguinal hernia. They affirm that appendicectomy and hernioplasty may be performed at the same time, since the repair of the hernia should be performed without prosthesis implantation due to the contamination of the operating field.

BackgroundGranular cell tumors (GCTs) were firstly described by Weber in 1854 and 70 years later by Abrikossoff and classified as benign tumors. Originally considered muscle tumors, they have been identified as neural lesions, due to their close association with nerve and to their immunohystochemical characteristics.GCTs are uncommon tumors and they may arise in any part of the body; they have been mainly observed in tongue, chest wall and upper extremities; less frequent sites are larynx, gastrointestinal tract, breast, pituitary stalk and the female anogenital region.Here we report a case of GCT showing an uncommon localization such as the upper third of the right rectus muscle of the abdominal wall.Case presentationA 45 year-old woman of Caucasian origin presented to the surgeon with a 6-month history of light pain in the upper third of the abdominal wall.Radiological exams (Ultrasonography, Computed Tomography and Contrast magnetic resonance imaging) showed a localized in the right rectus abdominis muscle.After excision, histological and immunohystochemical analysis, with the support of electron microscopy, allowed making diagnosis of granular cell tumor.DiscussionAfter fist description by Abrikosoff in 1926 of GCT like mesenchymal tumor of unknown origin, in recent years immunohystochemical techniques definitely demonstrated the histogenetic derivation of GCT from Schwann cells.Granular cell tumors are rare, small, slow-growing, solitary and painless subcutaneous nodules which behave in a benign fashion, but can have a tendency to recur; in rare cases they can metastasize, when they became malignant; there are some clinical and histological criteria to suspect the malignance of this tumor.ConclusionIt is important that clinicians, radiologists and pathologists are aware of the clinical presentation and histopathology of GCT for appropriate management, counselling and follow-up. In our case we had a complete radiological, morphological and immunohystochemical characterization of the lesion and a definitive diagnosis of benignity confirmed by electron microscopy.

Fifty-five patients with Graves' disease (GD) and mild to moderate Graves' ophthalmopathy (GO) underwent near-total thyroidectomy (Tx). In 16 patients this was followed by a standard ablative dose of (131)I because of the hystologic evidence of differentiated thyroid carcinoma. We retrospectively evaluated whether or not GO activity could be affected by thyroid surgery alone or followed by complete ablation of thyroid tissue. Accordingly, on the basis of clinical activity score (CAS) values prior to thyroidectomy, we identified two groups: group A with active GO (CAS > or = 3; n = 31) and group B with inactive GO (CAS < or = 2; n = 24). CAS values were then recorded at 6, 12, and 24 months after surgery/(131)I ablation. Over the course of the follow-up period, GO became inactive in approximately 70% of group A patients (CAS 4.2 +/- 0.8 at baseline, 2.1 +/- 2.0 at 24 months, p < 0.0001) and became active in 37.5% patients from group B. When we examined GO activity according to the type of treatment used (Tx or Tx and (131)I), the prevalence of inactive GO both short- and long-term, was significantly higher in the group of patients who underwent Tx and (131)I ablation. Therefore, this seems to be a more effective means of inducing and maintaining inactive GO.
