RESUMO

INTRODUCTION: Thyroid metastases from colorectal cancer are uncommon and few cases are described in literature. CASE PRESENTATION: A 64-year-old female patient presented with an asymptomatic right cervical nodule with a rapid growth six years after sigmoidectomy for cancer and two years after resection of colorectal lung metastases. Increased CA 19.9 was identified and a thoracoabdominal CT scan revealed the onset of new metastatic bilateral pulmonary lesions. Neck ultrasonography showed a suspicious nodule in the right thyroid lobe, and Fine-needle Aspiration Cytology (FNAC) of the nodule lead to the diagnosis of colorectal cancer metastasis. A right thyroid lobectomy with right central lymph node dissection was performed. The patient underwent chemotherapy with response, but this was posteriorly suspended due to haematological side effects, and the disease spread. DISCUSSION: Thyroid metastases from colorectal cancer are rare, but, with the improvement of radiologic exams and the higher survival rate of these patients, more cases are being described. The majority of the cases present pulmonary and hepatic metastases and the prognosis is poor. The decision to operate and the type of operation depend on the extent of the metastatic disease and the patient's overall condition. CONCLUSION: A low threshold of suspicion is crucial to make a timely diagnosis of thyroid metastases from colorectal cancer. Treatment is controversial, but, without surgery, the need may arise for tracheostomy.

RESUMO

INTRODUCTION: The ischaemic diabetic foot is associated with a faster evolving atherosclerosis affecting preferentially the bellow knee arteries. This distal ischemia associated with a wide distribution of multiple stenosis and occlusions throughout lower limb arteries, makes revascularization very hard or even impossible. This represents a major factor responsible for non-healing diabetic foot ulcer. In these cases all efforts should be made to find treatment alternatives that can promote ulcer healing. CASE PRESENTATION: Male patient with neuroischaemic diabetic foot ulcer with exposure tendon, without possibility for endovascular or surgical revascularization, was treated unsuccessfully with prostaglandin and several types of dressings for 7 months. Skin graft failed. Weekly dressings with collagen implant impregnated with gentamicin sulphate were then started and continued in an outpatient setting. Evolution was very positive, with 99% of epithelisation in 9 months. No pain or infection since the beginning of this treatment. DISCUSSION: Successful treatment of a neuroischaemic diabetic foot ulcer rests with the possibility of increasing the perfusion to the foot. Whether or not a revascularization procedure is possible will set the tone for the ensuing treatment. Using collagen implant with gentamicin sulphate, collagen is delivered to the wound bed helping in the granulation tissue formation, will increase microcirculation, and topic gentamicin will decrease bacterial load, exudate and proteases production, increasing cicatrisation. CONCLUSION: In neuroischaemic diabetic foot ulcer weekly dressings with collagen implant impregnated with gentamicin sulphate can be a good option for ulcer healing.

RESUMO

INTRODUCTION: Bochdalek hernia is one of the most common congenital abnormalities manifested in infants. In the adult is a rarity, with a prevalence of 0.17-6% of all diaphragmatic hernias. Right-sided Bochdalek hernias containing colon are even more rare, with no case described in the literature with ileo-cecal appendix. PRESENTATION OF CASE: The authors present a case of a right-sided Bochdalek hernia in an adult female of 49 years old, presented with severe respiratory failure. During laparotomy for hernia correction, were found in an intrathoracic position the cecum and ileo-cecal appendix, the right colon and the transverse colon. DISCUSSION: Although useful in patient evaluation, clinical history and physical examination are not helpful in making diagnosis because of their nonspecific character. CT scan is the most accurate exam for making diagnosis. Most of the times there is no hernial sac. Surgery is the treatment of choice, and it is always indicated even if asymptomatic. In general suture of the defect is possible. Due to patient's weak respiratory function we chose laparotomy by Kocher incision. CONCLUSION: Being the first case of a right-sided Bochdalek hernia in the adult with a herniated ileo-cecal appendix, we name it Almeida-Reis hernia.
