ABSTRACT
Facial metastasis from colorectal cancer is very unusual. Herein, we report a 53-year-old man with history of colon cancer who was referred to our clinic because of an asymptomatic nodule on his chin for one year. Histopathologic examination of the nodule revealed metastatic adenocarcinoma, which was similar to that of the primary colon adenocarcinoma. The patient underwent radiotherapy for his skin metastasis, but he died 13 months later from widespread metastasis
ABSTRACT
The aggravating role of Staphylococcus aureus is well known in atopic dermatitis but has not yet been proven in psoriasis. The role of Staphylococcus aureus superantigens is emphasized in the initiation, maintenance and complications of psoriasis. We investigated the frequency of nasal, axillary, and perineal carriage of Staphylococcus aureus [SA] in patients with psoriasis and its possible influence on the severity of the disease. One hundred patients with the clinical diagnosis of psoriasis participated in the study. Cultures of the bacterial flora were obtained from the right and left axilla and nasal nares and perineum, inoculated on standard bacterial medium [blood agar], and incubated at 37°C degrees for 48 h. One hundred patients with the clinical diagnosis of psoriasis [42% female and 58% male] comprised the study group. Mean age of the patients was 41.1 +/- 17.1 years. About 42% of the patients carried S. aureus; of these, 32% were from the nose, 13% from axilla, and 11% from the perineum. Three patients were carriers in all 3 sites. There was no significant difference in the severity of the disease between the carriers and non-carriers measured by the psoriasis area and severity index [PASI] score. According to our findings, S.aureus carriage in psoriasis had no significant influence on disease severity. It might be relevant for a subgroup of patients only when superantigen productions are found
ABSTRACT
Hydatid cyst mostly presents solitary cyst in right lobe of liver. It is asymptomatic and patient presents with pressure effects or rupture of cyst. We introduce a patient who was referred to the emergency room with history of blunt trauma and symptoms of abdominal pain and generalized severe pruritus without anaphylaxis and urticaria. Explorative laparotomy showed a ruptured hydatid cyst. Albendazole 400 milligram was prescribed twice a day for 4 weeks after operation. The patient discharged with healthy appearance. There was no abnormal findings in further followup visits

It is possible to use light sources such as lasers to destruct melanosomes and treat pigmented skin lesions. One of the most commonly used laser systems is Q switched ruby laser with a wave-length of 694 nm. This study was performed to evaluate the efficacy of the Q switched ruby laser in the treatment of pigmented skin lesions including lentigines [simplex or solar] and cafe-au-lait macules. After physical examination for ruling out the possibility of malignancy by two dermatologists, patients were treated with Q switched ruby laser. Response to treatment was categorized in four groups of equal interval according to the 0-100% lesion lightening. Ninety patients including 81 patients with solar lentigo and 9 cases of lentigo simplex were recruited into this study. Mean st and ard deviation [SD] of the number of treatment sessions for solar lentigo and lentigo simplex cases were 1.0 0.5 and 3.6 1.3 respectively. Although the mean of sessions was increased in darker skin types, there was no statistically significant difference between different skin types [p=0.335]. In addition, there was no significant relation between mean treatment sessions and location of the lesions [p=0.685]. Cure rate was 100% in all lentigo cases and after a mean SD of 8.7 2.3 months follow up there was no recurrence. Also, there was neither pigmentary change nor folliculitis during treatment. In 7 cases with cafe-au-lait macules, the mean SD score of improvement was 2.4 0.8, which was achieved after 3.1 0.4 treatment sessions. In 6 cases whom were followed up for 10.2 3.1 months, despite primary disappearance, recurrence of cafe-au-lait macules was observed. It seems Q switched ruby laser is an appropriate method for treatment of lentiginous lesions in Caucasians with Fitzpatrick's skin types II to IV
