[] Key Method Other symptoms included numbness of the hands, anorexia, weight loss, dizziness, fatigability and a sore mouth and tongue. There was no evidence of hypocortisolaemia and a literature search revealed a possible B12 deficiency. The patient had low serum B12 levels and megaloblastic anaemia. An intrinsic factor antibody test was negative. A gastric biopsy…

Pigmentation in vitamin B12 deficiency masquerading Addison's pigmentation: A rare presentation
TLDR
A 35-year-female presented with generalized weakness, weight loss, and progressive pigmentation was worked up for suspicion of Addisons disease and found to have megaloblastic anemia with a low serum vitamin B12, mostly due to poor dietary intake.
Generalized Hyperpigmentation of the Skin due to Vitamin B12 Deficiency
TLDR
It is considered that the dominant mechanism of hyperpigmentation due to vitamin B12 deficiency is not a defect in melanin transport but is rather an increase inmelanin synthesis.
A Reversible Cause of Skin Hyperpigmentation and Postural Hypotension
TLDR
Two patients with vitamin B12 deficiency presented with progressive darkening of hands and postural hypotension that reversed with replenishment of vitamin B 12 that shared many similarities with Addison disease.
Addisonian pigmentation and vitamin B₁₂ deficiency: a case series and review of the literature.
TLDR
The importance of testing vitamin B₁₂ levels in patients who present for evaluation of generalized hyperpigmentation is discussed, and various cutaneous changes related to the diagnosis are noted as incidental findings.

TLDR
There was no statistically significant difference in haematological, biochemical and histological parameters in IFA positive and negative gastritis, where H. pylori may be responsible for initiating the process.

TLDR

TLDR
The primary cause of folate deficiency is low intake of sources rich in the vitamin, such as legumes and green leafy vegetables, and the consumption of these foods may explain why folate status can be adequate in relatively poor populations.
