Vulvo-vaginal ano-gingival syndrome: Another variant of mucosal lichen planus.

Vulvo-vagino-gingival syndrome was described as a distinctive pattern of erosive plurimucosal lichen planus (LP), and it is a clinical triad of vulval, vaginal, and gingival LP. It can lead to sequelae such as vaginal and urethral stenosis which can have severe implications on the quality of life. We report a case of a 40-year-old female who developed urethral, vaginal, as well as anal stenosis as a result of long-term exclusive mucosal LP involving vulvo-vaginal and anal mucosa along with oral LP without any other cutaneous involvement. This case is being reported because of the rare association of anal LP with vulvo-vagino-gingival syndrome and its gross similarity to lichen sclerosus.

Pregnancy luteoma: A rare case report.

Pregnancy luteomas are rare, nonneoplastic lesions of the ovary thought to be caused by the hormonal effects of pregnancy. Most of these patients are asymptomatic with the ovarian enlargement being incidentally discovered during imaging or surgery. Some patients develop hirsutism or virilization during late pregnancy. Luteomas spontaneously regress postpartum. It may be a diagnostic and management challenge as it can mimic the presentation of malignant ovarian tumors. We present a 33-year-old female with an enlarged ovary discovered incidentally at the time of cesarean section.

Linear porokeratosis.

Linear porokeratosis is a rare variant. It can be present at birth or can develop in adult life. Lesions of linear porokeratosis are grouped and linearly arranged along the lines of Blaschko. On the extremities it affects the distal portion more than the proximal areas. On the trunk these can be zosteriform in distribution. Lesions of linear porokeratosis probably result from an abnormal clone of epidermal precursors. A 20 year old male presented with annular plaques in linear pattern following the lines of Blaschko over the left upper limb extending up to the axilla present since childhood. The lesions had atrophic centre and raised hyperkeratotic borders. The lesions were more proximal than distal. Few scattered lesions were present on left side of trunk. There was no family history of such lesions. Systemic examination of patient was normal. On histopathological examination there was hyperkeratosis and parakeratosis. A coronoid lamella was present. At the base of coronoid lamella thinned out granular layer and necrotic keratinocytes were also seen. In the dermis pigment incontinence and perivascular lymphocytic infiltrate were present. This case is being reported because of its rarity. It is an atypical presentation because the lesions were disposed more over proximal than distal area of upper limb. Linear porokeratosis is associated with an increased risk of malignant transformation.

The effect of alpha adrenergic blockade on non-specific airways reactivity and exercise induced asthma.

In asthmatics, alpha-adrenergic blockage with oral phentolamine partially or completely blocked bronchospasm after maximal exercise challenge. Bronchial reactivity to isocapnic hyperventilation with conditioned cold air was also reduced. However, non-specific airways reactivity to inhaled histamine did not change. Therefore, exercise and cold induced bronchospasm in asthma may be partially mediated by alpha adrenergic neural mechanisms perhaps through sensitization of alpha receptors during airway cooling.
