Eccrine squamous syringometaplasia is characterized by the metaplasia of cuboidal epithelial cells of the eccrine sweat ducts into squamous epithelial cells. It has been associated with several ...conditions including chemotherapy‐related bilateral dermatitis, an entity that can take place in body areas rich in eccrine glands, as well as in acral erythema related to chemotherapy. Only a few cases because of cutaneous extravasation of chemotherapy have been previously reported. We report three cases of eccrine squamous syringometaplasia secondary to extravasation of docetaxel.
Infectious pseudochromhidrosis is a rare dermatological disorder, characterized by a change in colour of the sweat from normal skin, caused by pigments from microorganisms. Such pigments are a result ...of evolutionary competition among microorganisms, which appears to be a decisive factor in their survival, patho-genicity, and virulence. Four bacteria are known to be involved in infectious pseudochromhidrosis: Bacillus spp. (blue colour), Corynebacterium spp. (brown/black colour), Serratia marcescens (red/pink colour), and Pseudomonas aeruginosa (blue-green colour). Infectious pseudochromhidrosis seems to be triggered by certain drugs and conditions causing physiological alterations and/or changes in microflora on the skin surface. The condition can be treated by addressing potential triggers and/or prescribing antibiotic/antiseptic therapies. We report here a case of blue infectious pseudochromhidrosis caused by pigment-producing Bacillus cereus and the results of a literature review.
Apocrine chromhidrosis is a very rare, idiopathic disorder of the sweat glands characterized by the secretion of colored sweat. Because hormonal induction increases sweating, the symptoms of apocrine ...chromhidrosis usually begin after puberty. Although treatment may not be necessary in some cases, capsaicin cream and 20% aluminum chloride hexahydrate solution have been successfully used to treat patients requiring intervention. Here we report four cases with apocrine chromhidrosis. To the best of our knowledge, our patients are the youngest cases reported in the literature.
Background
Axillary bromhidrosis is a condition presenting as malodor caused by an interaction between the discharge of apocrine glands and bacteria. Topical agents, liposuction, and elective surgery ...are currently the main therapeutic modalities. However, the efficiency of these treatments and incidences of side effects are various and frequent, and depend on patient characteristics, surgical technique, and other unknown factors.
Methods
We report a retrospective study of outcomes in 396 patients treated by mini‐incision with subdermal vascular preservation.
Results
At 2 years postoperatively, 87.1% of patients had achieved very satisfactory results. Short‐term side effects included hematomas, epidermal erosions, infections, necrosis, incision dehiscence, and skin ripples. Long‐term side effects comprised comedones, epidermoid cysts, relapsing cyst infections, skin gauffers, scars, keloids, and persistent malodor. Some patients reported unsatisfactory cosmetic results, including skin gauffers, scars, or epidermoid cyst formations.
Conclusions
Two discrete aspects of the procedure that must be considered are the extent of apocrine gland clearance, which must be thorough in order to achieve the resolution of malodor, and the maintenance of an intact subdermal vascular plexus to support the regrowth of skin flaps after surgery and to avoid the occurrence of severe side effects.
...porokeratotic adnexal ostial nevus is considered a more unifying term for these conditions. Porokeratotic adnexal ostial nevus needs to be differentiated from linear porokeratosis, focal dermal ...hypoplasia, inflammatory linear verrucous epidermal nevus, linear psoriasis, linear Darier's disease, linear hypertrophic lichen planus and curvilinear ichthyosis in Conradi- Hünermann syndrome, CHILD syndrome (Congenital hemidysplasia with ichthyosiform erythroderma and limb defects) and nevus comedonicus. Numerous densely packed distinct white dots that most possibly represented dilated and hypertrophic appendageal ducts are major histological finding in porokeratotic adnexal ostial nevus that is detected under the dermatoscope. ...dermatoscopy can be an important noninvasive alternate tool to elicit these abnormalities in porokeratotic adnexal ostial nevus.
